      Fact Checking Nikki Haley’s DeSantis Lies Website

      by

      During this week’s debate in Iowa, Nikki Haley, the former governor of South Carolina, tirelessly promoted a website to fact-check Gov. Ron DeSantis of Florida. We took a closer look, and here’s what we found.More than a dozen times during Wednesday night’s Republican presidential debate, Nikki Haley, the former governor of South Carolina, directed viewers to a website purporting to correct what she called Ron DeSantis’s “lies.”But the Haley campaign’s website is itself a political project — not an exercise in objective fact-checking.The site does point to independent fact-checking to help push back on claims twisting Ms. Haley’s positions on things like Gaza refugees and to clarify her comments about being motivated to run for office by a speech made by Hillary Clinton, despite their political differences.But there are key differences between Ms. Haley’s effort and an independent fact-checking operation. The website, for example, doesn’t directly quote Mr. DeSantis or cite the specific comments being rebutted. It also deems a “lie” some statements that don’t actually contain checkable facts.“Mr. DeSantis claims he will take on the big spenders in Washington,” the site says, calling his claim a lie because while in Congress he voted to increase the federal debt limit. Ms. Haley may well use that line of criticism in her campaign, but that alone doesn’t make Mr. DeSantis’s statements about his intent to rein in federal spending a “lie.”“Ultimately it’s still campaign propaganda,” said Bill Adair, the creator of the website PolitiFact and a Duke University journalism professor. “It’s not fact-checking.”It’s certainly not the first time a political campaign has harnessed the style of fact-checking for its own objectives, Mr. Adair said, noting that the 2008 Obama campaign created a website to push back against “smears.”On the debate stage Wednesday, “it was just trumpeted more prominently and more often than I’ve ever seen it before,” Mr. Adair said. He added: “I think that shows that fact-checking has matured to the point where candidates are pretending to be fact checkers to try to give their own account of facts, although often it’s not the full truth.”Here’s further context on several of the claims made on Ms. Haley’s website, Desantislies.com.Gender-transition careThe website states that “DeSantis falsely claims Nikki Haley supports gender-changing surgeries for minors.” It goes on to say that, in fact, Ms. Haley “opposes gender-changing surgeries and puberty blockers for minors and is on record saying as much multiple times.”It is true that Ms. Haley has spoken out against minors being able to undergo gender-transition surgeries before the age of 18. But Mr. DeSantis and other critics have homed in on a comment she made in June — not mentioned on Ms. Haley’s website — suggesting that the law should not be involved in regulating such care.During a CBS interview, Ms. Haley was asked what the law should say regarding transgender care for youths. “I think the law should stay out of it, and I think parents should handle it,” Ms. Haley responded.Still, even then, Ms. Haley added that “when that child becomes 18, if they want to make more of a permanent change they can do that.”Free speechThe website says that “DeSantis falsely claims Haley opposes free speech on social media,” and points out that Mr. DeSantis previously expressed support for legal efforts to crack down on journalists’ use of anonymous sources.But the site ignores that Ms. Haley did in November call for requiring social media users to be verified by name, before walking back her comments amid criticism.“When I get into office, the first thing we have to do, social media accounts, social media companies, they have to show America their algorithms,” Ms. Haley said during a Fox News event. “Let us see why they’re pushing what they’re pushing. The second thing is every person on social media should be verified by their name.”Ms. Haley added: “First of all, it’s a national security threat. When you do that, all of a sudden people have to stand by what they say. And it gets rid of the Russian bots, the Iranian bots and the Chinese bots. And then you’re going to get some civility when people know their name is next to what they say, and they know their pastor and their family members are going to see it.”Mr. DeSantis quickly criticized her comments, saying, “Haley’s proposal to ban anonymous speech online — similar to what China recently did — is dangerous and unconstitutional.”A day later, Ms. Haley said on CNBC that “life would be more civil” if people did not post anonymously, but noted: “I don’t mind anonymous American people having free speech. What I don’t like is anonymous Russians and Chinese and Iranians having free speech.”Confronted during the December Republican debate, Ms. Haley misleadingly claimed she “never said government should go and require anyone’s name.”TaxesMr. DeSantis and his supporters have made misleading claims about Ms. Haley’s record on taxes while she was governor of South Carolina. But the claims weren’t always found to be categorically false, as Ms. Haley’s website contends.The website links to four articles, including two from The New York Times. In one example, The Times fact-checked a pro-DeSantis super PAC’s argument that Ms. Haley “raised taxes” and found it to be misleading.That’s because, technically speaking, Ms. Haley cosponsored legislation passed in 2006 that did raise the state sales tax by one percentage point. But that measure also exempted owner-occupants from paying property taxes for schools — among other provisions — and was considered by experts to be a “tax swap,” not a tax increase. An analysis at the time projected that most homeowners would have an overall decreased tax burden.ChinaCalling Ms. Haley the “most outspoken candidate on the growing China threat,” the website claims that “DeSantis falsely attacks Nikki Haley’s record on China.”There have indeed been distortions: Mr. DeSantis claimed that Ms. Haley gave a Chinese company land near a military base, referring to a fiberglass company. But while Ms. Haley celebrated the company’s opening of a plant in South Carolina, and although the state provided a grant for improving the site, it was the county government — not the state — that provided the land as part of a deal to secure hundreds of jobs.But it’s worth noting that the flawed attacks have gone both ways.For example, a pro-Haley super PAC wrongly claimed that Mr. DeSantis “voted to fast-track Obama’s Chinese trade deals.” That claim was based on a vote Mr. DeSantis took as a congressman in 2015 to extend the president’s authority to fast-track trade legislation (he was among 190 Republicans in the House to vote for it). No trade agreements subject to that authority were made with China. More

      Christie’s Exit Should Give Haley a Chance in New Hampshire. Will It Be Enough?

      by

      A group of moderate voters is now available, but it may not put her over the top against Trump.Chris Christie and Nikki Haley on a debate stage last month.Gerald Herbert/Associated PressEight years ago, Chris Christie gave Donald J. Trump the biggest political assist of the 2016 campaign.He eviscerated a surging Marco Rubio on the debate stage just days before the New Hampshire primary. In doing so, he ensured that the Republican mainstream would be divided and allowed Mr. Trump to regain his footing with a win after a loss in Iowa.Mr. Trump won’t be getting the same favor again.On Wednesday, Mr. Christie withdrew from the race. Whatever his intent, by bowing out he has effectively done what he didn’t do eight years ago: step out of the way of a mainstream conservative with moderate appeal, in this case Nikki Haley, who is surging heading into the New Hampshire primary.In the most recent polls, she reached about 30 percent of the vote in New Hampshire. It was a tally that put her within striking distance of Mr. Trump and even made a victory imaginable. But she still trailed by about 12 percentage points, and her path to victory remained quite narrow.With Mr. Christie out of the race, those 12 points don’t look so hard anymore. Mr. Christie has held around 10 percent of the vote in New Hampshire for months, and Ms. Haley and Mr. Trump would essentially be tied in New Hampshire if her support were hypothetically combined with Mr. Christie’s.According to FiveThirtyEight on Wednesday night, Ms. Haley and Mr. Christie’s support added up to 41.5 percent of the vote in New Hampshire, to 42.4 percent for Mr. Trump.Of course, not every one of Mr. Christie’s voters will back Ms. Haley. But in this particular case, there’s good reason to think the preponderance of his voters really will coalesce behind her.Mr. Christie is the only vocal anti-Trump candidate and, not surprisingly, his supporters are the likeliest to be anti-Trump. In a CNN/UNH poll this week, 65 percent of Mr. Christie’s supporters said Ms. Haley was their second choice. In a CBS/YouGov poll last month, 75 percent of Mr. Christie’s supporters in New Hampshire said they would consider Ms. Haley. Just 9 percent said they would consider Mr. Trump.With these numbers, Ms. Haley’s path to victory isn’t like hitting an inside straight — it is fairly straightforward. No, the Christie vote, alone, will probably not be enough. But she has been steadily gaining in the polls and, historically, there’s a lot of precedent for surging candidates to keep gaining — especially over a contest’s final days. With Mr. Trump at just 42 percent of the vote, there’s no reason to think her path is closed off.Of course, a Haley win in New Hampshire would not mean that Mr. Trump’s path to the nomination was in jeopardy. Not even Mr. Christie seems optimistic about her chances; he was heard on a hot mic Wednesday saying “she’s going to get smoked,” presumably referring to Ms. Haley, and he did not endorse her.Her appeal is concentrated among highly educated and moderate voters, who represent an outsize share of the electorate in New Hampshire. She also depends on the support of registered independents — in some other key primary contests, they are not eligible to vote. Back in 2016, moderate candidates who went nowhere nationally — John Kasich, Mr. Christie and Jeb Bush — added up to 34 percent of the vote in New Hampshire. If you add the 11 percent held by Mr. Rubio, a mainstream conservative, that’s 45 percent of the vote that went for establishment candidates. In other words, this state is not representative of the Republican electorate.But this time, the voters who backed those moderate Republicans will have a chance to coalesce behind a single candidate and, in doing so, deal a blow to Mr. Trump. The consequences may mostly prove to be symbolic: a rare Republican rebuke of Mr. Trump and a reminder that the old mainstream of the Republican Party remains to be reckoned with.But there is a chance, albeit a small one, that a Haley win in New Hampshire would prove to be more important. Mr. Trump may face criminal trials in the months ahead. While it seems exceedingly unlikely today, an erosion of his aura of dominance might make him ever so slightly more vulnerable if a trial gets underway. More

      With Chris Christie Out, Nikki Haley Is Poised to Benefit in New Hampshire

      by

      Ms. Haley has cut into former President Donald J. Trump’s lead in the state where Mr. Christie had spent significant time wooing voters opposed to Mr. Trump.The former New Jersey governor Chris Christie’s decision on Wednesday to drop out of the presidential race shook up a contest for the Republican nomination that had appeared to be former President Donald J. Trump’s for the taking, giving a huge shot of adrenaline to Nikki Haley just five days before ballots begin to be cast in the monthslong nomination fight.The most obviously altered battleground is likely to be New Hampshire, where Ms. Haley, the former governor of South Carolina and Mr. Trump’s first ambassador to the United Nations, is within striking distance of the former president. Even without his endorsement, many New Hampshire voters who planned to side with Mr. Christie as an opponent of Mr. Trump’s are likely to flip to Ms. Haley, as is potentially some of Mr. Christie’s leadership team.But the jolt will have much broader implications, argued John Sununu, a former New Hampshire senator and the brother of the current governor, Chris Sununu, both of whom have endorsed Ms. Haley. A contest that has centered on Mr. Trump’s return and the fight between Ms. Haley and Gov. Ron DeSantis of Florida for second place will now focus squarely on the threat Ms. Haley poses to Mr. Trump’s coronation.A memo that Mr. Trump’s campaign blasted out after Christie’s announcement on Wednesday night did just that, broadcasting what it called internal polling that showed Mr. Trump beating Ms. Haley in a head-to-head contest 56 percent to 40 percent.We are having trouble retrieving the article content.Please enable JavaScript in your browser settings.Thank you for your patience while we verify access.

      Will You Vote for Trump Again?

      by

      Jesse Gutierres believes only one Republican candidate will restore confidence in the economy.Kelly Nieuwenhuis wants to move beyond the chaos.Shannon Demastus wants a president she can be proud of.Will You Vote for Trump Again?It’s the question weighing on Republicans across the country. But Iowans get to decide first. We listened as they grappled with their choices.Jan. 11, 2024There is no way around it: The Iowa caucuses on Monday, the kickoff of the 2024 presidential election, are not really about competing visions for the future of the Republican Party. They are not a battle between dueling ideologies or policy priorities or America’s role in the world.They revolve around one man, the gravitational center of Republican politics for nearly a decade: the former — and perhaps future — President Donald J. Trump.Republicans are in the throes of deciding whether they want Mr. Trump to continue his total dominance over their party. Do they want four more years of his brand of personality-driven, divisive and combative politics? Do they see him as a victim, or as a demagogue? Are they willing to risk nominating a candidate facing 91 charges and who could be a felon come Election Day?Polling shows Republicans are preparing to take the leap; Mr. Trump appears to likely win in Iowa. But the numbers don’t capture the ambivalence and anxiety weighing on many as they grapple with their decisions.We are having trouble retrieving the article content.Please enable JavaScript in your browser settings.Thank you for your patience while we verify access.

      Haley and DeSantis Summon the Right Fury for the Wrong Target

      by

      I wish Nikki Haley and Ron DeSantis had shown a quarter as much contempt for Donald Trump as they did for each other.Oh, they faulted Trump for not appearing onstage in Des Moines on Wednesday for the final Republican presidential debate before the Iowa caucuses. He arrogantly skipped it, just as he’d arrogantly skipped all the others.When pressed, Haley and DeSantis made clearer than they did in the past that he indeed put himself before the Constitution when he tried to overturn the results of the 2020 election and that what happened on Jan. 6, 2021, was no beautiful display of patriotism. It was a shameful act of disorder.And they had scattered other criticisms of the former president. DeSantis listed many of the promises that Trump didn’t keep. Haley blamed Trump for the depth and breadth of the divisions in America and for creating a degree of chaos that forbids meaningful progress.But those complaints all but receded behind their furious, puerile and relentless attacks on each other. And that made neither political nor moral sense.Haley and DeSantis are the only candidates other than Trump who qualified for the debate. They are the only candidates with any chance of beating him in the Republican primaries and getting the party’s presidential nomination. But that chance is meager, the clock is ticking, and Trump, to go by polls, has held on firmly to his enormous lead. They need to take him down.And for all their considerable flaws, all their embarrassing flubs and all their elaborate fudging of their records, both Haley and DeSantis have infinitely less to account and apologize for than Trump does. He’s the necessary target of their wrath, the rightful recipient of their disdain, an urgent threat to American democracy. But you wouldn’t have known that from the small fraction of their attention that he received, an inadequate measure that distills the Republican Party’s disgrace. It won’t own or slay the monster it created. It’s just too damned terrified.Instead, Haley and DeSantis engaged in a rubber-glue back-and-forth about who was the bigger liar. I can recap almost the entire debate in just a few lines of loosely (but not all that loosely!) paraphrased dialogue.Haley: Stop lying about me!DeSantis: No, you stop lying about me!Haley: You’re the liar!DeSantis: I know you are, but what am I?Haley: You’re so desperate. You’re just so desperate.Haley actually said those last two sentences. And they were strangely refreshing inasmuch as they weren’t one of her endlessly repeated instructions to go to the website desantislies.com. She mentioned that site seemingly every 30 seconds, regardless of what question the debate’s moderators had put to her. She was like a broken GPS system. No matter where you asked her to take you, she directed you to the same old place.DeSantis wasn’t any more high-minded. He banged on and on about what a sellout Haley was, about how she was constantly caving to big business or “the woke mob” or the Chinese. He was especially and inexplicably fond of a line that he used in various ways at various times — that she embodied the “pale pastels” of “warmed-over corporatism.” Was he upset that her corporatism wasn’t freshly sautéed? Was he claiming a sartorial edge and asserting some parable in the contrast between his red tie and her muted pink dress? Color me unimpressed.Except for when DeSantis, whose scripted lines were mostly clichés, delivered one of anomalous cleverness. Referring to Haley’s recent string of highly publicized gaffes, he said, “She’s got this problem with ballistic podiatry — shooting herself in the foot.”Funny as that was, it was even sadder because it was an example of how and where these two candidates lavished their energy: not on sounding the alarm about Trump that needs sounding (and re-sounding), not on holding themselves up as inspiring alternatives to him but on cutting each other down. That was clearly what they’d practiced most. Scorn was their comfort zone.So when they were asked, in the final minutes, to name something about the other that they admired, they lapsed into babble and incoherence.After a few compulsory words about Haley’s service as the U.S. ambassador to the United Nations, DeSantis said: “I also appreciate the state of South Carolina. My wife is a College of Charleston graduate.” So Haley is admirable because she’s proximal to Casey DeSantis’s alma mater?Haley’s answer — “I think he’s been a good governor” — made even less sense, because she had just spent the better part of two hours talking about all the ways in which he’d been a terrible leader for Florida and how awful it would be if he molded America in his state’s image.They did indeed engage in specifics like that, providing details about their own and each other’s records, establishing an important divergence in their views on aid to Ukraine, forecasting the future of Social Security and promising to fortify the country’s southwestern border. From time to time, the two of them engaged in something not all that dissimilar from a constructive old-fashioned debate.But that was the exception to the rule and to the rancor, and what stood out more than any policy discussion was a depressing paradox: Both of them said that America needed to turn the page, but both modeled the negativity, mockery and spite of the country’s current chapter.“How did you blow through $150 million in your campaign, and you were down in the polls?” Haley asked DeSantis. She visibly relished her dig. Where was that ridicule for Trump?Chris Christie, we miss you! Hours before the debate, which Christie hadn’t qualified for, he dropped out of the race, and he was caught in a hot mic moment, apparently dismissing Haley as “not up to this” and saying that DeSantis was “petrified” about the trajectory of the race. Their performances on Wednesday night bore Christie out. Send him to Delphi and put him in a cave. He’s an oracle.I invite you to sign up for my free weekly email newsletter.

      Chris Christie Goes Down Swinging at Trump and Pleading With His Party

      by

      Chris Christie closed out his second presidential campaign much as he began it, with a blistering and personal takedown of Donald J. Trump designed to prompt a reckoning in his party.Anticipation had been building all day for the remarks from Mr. Christie, a former governor of New Jersey, after news had spilled out hours earlier that he was telling close allies about his decision.With all three major cable news networks airing the speech live, Mr. Christie used the rare spotlight — something that had largely eluded his campaign — to make an urgent appeal to the better angels of his party. He framed his animosity toward Mr. Trump in sweeping, historical terms and cast himself as the experienced party elder warning of the possible dangers ahead.“Imagine just for a moment if 9/11 had happened with Donald Trump behind the desk,” Mr. Christie said. “The first thing he would have done was run to the bunker to protect himself. He would have put himself first before this country, and anyone who is unwilling to say that he is unfit to be president of the United States is unfit themselves to be president of the United States.”Mr. Trump’s campaign responded with a memo from his pollster, John McLaughlin, who said Mr. Christie “was going to be embarrassed” by the results of the Iowa caucuses on Monday and that he was “widely disliked” by voters in New Hampshire, which will hold its primary on Jan. 23. Mr. Christie had focused his campaign on New Hampshire, but struggled to make himself a contender.Mr. Christie also grappled with his own role in Mr. Trump’s rise, acknowledging that he had capitulated to ambition when he ended his 2016 presidential bid and surprised much of the political establishment at the time by backing Mr. Trump. Mr. Christie described his second campaign as something of a redemption tour.“I would rather lose by telling the truth than lie in order to win, and I feel no differently today, because this is a fight for the soul of our party and the soul of our country,” he said.Mr. Christie paced the stage as he spoke and at times appeared emotional, including when he talked about the supporters who had urged him to remain in the race. His voice cracked when he quoted Benjamin Franklin’s warning that Americans had been given “a republic, if you can keep it.”“Benjamin Franklin’s words were never more relevant in America than they are right now,” Mr. Christie said. “The last time they were this relevant was the Civil War.”Mr. Christie didn’t spare his rivals in the race, saying in public what he had expressed to others in private: that neither Gov. Ron DeSantis of Florida nor former Gov. Nikki Haley of South Carolina was going hard enough at Mr. Trump.He said that if Mr. Trump became the nominee, his win would be traceable to the first Republican debate. Mr. Christie was the only candidate on the stage who indicated that he would not support the former president if Mr. Trump were convicted of one of the 91 felony charges he is facing.“I want you to imagine for a second that Jefferson and Hamilton and Adams and Washington and Franklin were sitting here tonight,” Mr. Christie said. “Do you think they could imagine that the country they risked their lives to create would actually be having a conversation about whether a convicted criminal should be president of the United States?”But Mr. Christie’s speech is unlikely to move the needle inside the Republican Party. Many of the party’s most towering figures have tried in recent years without success.In 2016, Mitt Romney used his stature as Republicans’ previous presidential nominee to denounce Mr. Trump as a “fraud” whose promises were “worthless” and who was “playing the American public for suckers.” Mr. Trump won the nomination, and the White House.After the attack on the Capitol on Jan. 6, 2021, Senator Mitch McConnell, the Republican leader, spoke from the Senate floor to say Mr. Trump’s supporters involved in the attack had been “fed lies” and “provoked by the president.” Mr. Trump was later acquitted in an impeachment trial in the Senate, a decision supported by Mr. McConnell.Two years ago, Representative Liz Cheney of Wyoming, speaking from the Ronald Reagan Presidential Library, said Mr. Trump was “attempting to unravel the foundations of our constitutional republic” and had “gone to war with the rule of law.”She was unseated by a Trump-backed primary challenger months later.Alyce McFadden More

      Chris Christie Drops Out of 2024 Presidential Race

      by

      Former Gov. Chris Christie of New Jersey suspended his presidential campaign on Wednesday, but he undermined his effort to stop Donald J. Trump when he sweepingly dismissed his Republican rivals during a hot-mic moment.Minutes before his announcement in Windham, N.H., Mr. Christie could be heard on the event’s livestream, saying, “She’s going to get smoked, and you and I both know it,” in a reference to Nikki Haley, the former South Carolina governor. “She’s not up to this.” He added of Gov. Ron DeSantis of Florida, “DeSantis called me, petrified.”Mr. Trump immediately seized on the remarks, writing on Truth Social that Mr. Christie’s comments about Ms. Haley, who appears to be the most significant obstacle to a Trump victory in New Hampshire, were a “very truthful statement.”In his speech, Mr. Christie did not endorse any of his rivals, nor did he address their prospects against Mr. Trump, dashing the hopes of Republican moderates that his exit would unify remaining members of the party who oppose Mr. Trump.In fact, Mr. Christie denounced his opponents’ long-running public deference to the former president, and offered no positive remarks about their candidacies.“I would rather lose by telling the truth than lie in order to win,” he said. “And I feel no differently today because this is a fight for the soul of our party and the soul of our country.”His departure, which came after mounting pressure from within his party, effectively ends a phase of the Republican presidential contest, removing from the field its most aggressive Trump critic. He was the only prominent contender who declared that Mr. Trump was unfit for office — an argument that all but doomed his candidacy from the start.Nonetheless, Mr. Christie used the final moments of his campaign to unleash one last extended criticism of Mr. Trump, eviscerating his policies, lamenting the direction in which he has taken the country and asserting that he did not have the nation’s best interests at heart.Former Gov. Chris Christie of New Jersey was caught on a hot mic saying that a Republican presidential rival was “not up to this,” presumably referring to former Gov. Nikki Haley of South Carolina.“Imagine just for a moment if 9/11 had happened with Donald Trump behind the desk,” Mr. Christie said. “The first thing he would have done was run to the bunker to protect himself. He would have put himself first, before this country.”His speech doubled as a dark warning for a party — and a country — that the former governor portrayed as veering dangerously off course, criticizing “the hate and the division and the selfishness of what our party has become under Donald Trump.”Mr. Christie also acknowledged regret for his actions after Mr. Trump defeated him in the 2016 primary race. Soon afterward, Mr. Christie shocked the political establishment by endorsing Mr. Trump, becoming the first significant former candidate to back him as his march to the nomination picked up pace.“For all the people who have been in this race, who have put their own personal ambition ahead of what’s right, they will ultimately have to answer the same questions that I had to answer after my decision in 2016,” he said. “Those questions don’t ever leave. In fact, they’re really stubborn. They stay.”Despite Mr. Christie’s withering criticisms of his rivals, his decision could turn the primary election in New Hampshire on Jan. 23 into a two-person race between Mr. Trump and Ms. Haley. Her positions on foreign policy, national security and the rule of law broadly overlap with Mr. Christie’s, and she will hope to consolidate never-Trump Republicans and independents behind her.After Mr. Christie’s speech, Ms. Haley praised him as “a friend for many years,” commending him in a statement “on a hard-fought campaign” but making no reference to the hot-mic comments. “I will fight to earn every vote,” she said.On Wednesday, Mr. DeSantis had called Mr. Christie to express his appreciation for his role in the contest, according to two people with knowledge of the call. During their conversation, Mr. Christie mocked Ms. Haley and said she was not up to the task, the people said.Mr. DeSantis wrote on social media on Wednesday, “I agree with Christie that Nikki Haley is ‘going to get smoked.’”Recent polls have shown Ms. Haley narrowing the gap against Mr. Trump in New Hampshire, and her backing combined with Mr. Christie’s support has sometimes equaled or bettered the former president’s. A CNN/University of New Hampshire poll released Tuesday found Mr. Trump with 39 percent support, Ms. Haley with 32 percent and Mr. Christie with 12 percent.Mr. Christie, a former United States attorney, built his candidacy around a prosecutorial argument about his domineering rival’s unsuitability for office. He steadfastly refused to water down his denunciations of Mr. Trump, a onetime ally turned bitter antagonist, even as most of his rivals labored to find a middle ground of praise and subtle contrasts.Mr. Christie and wife Mary Pat Christie hugged supporters after his announcement on Wednesday.Sophie Park for The New York TimesThat bold stance, and Republican voters’ lack of tolerance for it, left Mr. Christie trailing far behind in polls and fund-raising, managing to grab a foothold only in independent-minded New Hampshire. Yet the former governor regularly found himself in the shadow of Ms. Haley in the Granite State during the closing months of the campaign, with Gov. Chris Sununu endorsing Ms. Haley in December and later calling on Mr. Christie to withdraw from the race.For weeks, Mr. Christie rebuffed any suggestion that he should drop out, stressing the argument that his role as Mr. Trump’s chief critic in a dwindling Republican field was vital.As recently as Tuesday, he spoke at length about his reasons for forging ahead.“Let’s say I dropped out of the race right now, and I supported Nikki Haley,” he said. “And then three months from now, four months from now, we get ready to go to the convention. She comes out and is his vice president. What would it look like? What will all the people who supported her at my behest look like when she’s up on a stage in Milwaukee with her hands up like this with Donald Trump?”Mr. Christie’s familiarity with the former president gave him endless ammunition for attacks. He mocked Mr. Trump’s taste for well-done hamburgers and his love of cable news. He called attention to Mr. Trump’s criminal indictments, even as other Republican candidates sought to support the former president through his legal woes.But despite this barrage, Mr. Christie’s condemnation of Mr. Trump never took hold. He made a cringeworthy attempt to nickname his rival “Donald Duck” over Mr. Trump’s ducking of the primary debates. He was drowned out with resounding boos during the first debate when he tried to criticize Mr. Trump.In an attempt to show both expertise in foreign policy and a fearlessness to lead, Mr. Christie embarked on trips to conflict zones in Ukraine and Israel. He vividly recounted atrocities he had learned about in each place to buttress his aggressive support of those countries, though neither overseas venture broke through with voters.As he campaigned, Mr. Christie became more moderate than he had been in the past, either admitting to mistakes like endorsing Mr. Trump or evolving on issues such as same-sex marriage. “I was wrong,” Mr. Christie said of his opposition to such marriages at an event in New Hampshire last month. He peppered his stump speeches with references to former President George W. Bush, hardly a popular figure with today’s Republican base.Betting his entire campaign on New Hampshire, Mr. Christie argued in an interview with The New York Times in September that “once Donald Trump loses in one place, that entire rotted building will crumble.” He held dozens of town halls and other events across the small state, building modest traction and rising in polls, though he never came within striking distance of Mr. Trump. Mr. Christie’s allied super PAC dumped all of its advertising budget — $5.1 million as of Wednesday, according to AdImpact, a media-tracking firm — into the state.Some of Mr. Christie’s supporters expressed disappointment after his event on Wednesday. Toni Pappas, a Hillsborough County commissioner from Manchester, N.H., was one of them, but said, “I think he did something very noble and patriotic.”Tom Barton, a self-described libertarian from Washington, N.H., who planned to vote for Mr. Christie, said he could not see himself supporting another Republican. “They don’t have the courage to tell the truth about Trump,” he said.Still, most Republican voters had remained firmly opposed to Mr. Christie, who trudged on without changing his approach. If anything, his resolve to attack the former president increased.“The future of this country is going to be determined here,” Mr. Christie told a crowd at a New Hampshire brewery in September, clutching an I.P.A.
