Politics is a tough business, so you’d think most politicians would be tough people. In fact, in my experience they’re often not. A lot of people go into politics because they want to be universally liked, and from Abraham Lincoln on down, many of them have detested personal confrontation. Several years ago it occurred to me that in every administration I had covered to that point — from Reagan through Obama — the White House staff seemed to fear the first lady more than they feared the commander in chief.This has obviously changed in recent times. Donald Trump was tough, mean and self-pitying (a nifty combination). President Biden is tougher than he looks. And the woman who is now Trump’s chief challenger, Nikki Haley, is one of the toughest politicians in America — by which I mean confrontational, willing to hammer her foes.When you read accounts of her days in South Carolina, her bellicosity fairly ripples off the pages. In a fantastic 2021 profile in Politico Magazine, Tim Alberta quotes a former South Carolina Republican Party chair: “Listen, man. She will cut you to pieces. Nikki Haley has a memory. She has a memory. She will remember who was with her and who was against her. And she won’t give a second chance to anyone who she thinks did her wrong.”But the most telling quotation is the one Haley gave to Alberta herself: “I don’t trust, because I’ve never been given a reason to trust.”She grew up in the only Indian American family in a small working-class South Carolina town. The stories she tells about her girlhood are often about exclusion: being disqualified from a beauty pageant because it was set up to allow for only one Black and one white winner (though some locals dispute this); a fruit-stand vendor calling the cops because her father was a brown-skinned man wearing a turban. She once described her childhood as “survival mode.”Today, many people think of Haley as part of the older Republican establishment, a political descendant of the Bushes and Mitt Romney who suddenly finds herself trying to thrive in a party dominated by Trumpian populists. This is not quite right. Haley entered politics as a Tea Party maverick. As Hanna Rosin noted in The Atlantic in 2011, the Tea Party was female-led, and most of its supporters were right-wing women who, among other things, wanted to take on the Republican old boys network. Women like Haley and Sarah Palin presented themselves as whistle-blowers, taking down corruption.Haley ran her first campaign, for state legislature, against a 30-year Republican incumbent. What ensued was classic South Carolina politics. A mailer went out attacking her and referring to her by her birth name, Nimrata Randhawa. A whisper campaign suggested she was Buddhist or Hindu. (In fact, she is a Christian who attends a Methodist church). When she got to the legislature, she didn’t fit in with the old guard. “I’m telling you, nobody liked her. Nobody wanted to work with her. They hated her,” another state representative, who became a close friend, told Alberta.Alberta captured this period of her career this way: “She came to be loathed by many of her fellow Republicans for not being a team player, for going rogue on certain votes and procedures that made them look slimy or stupid to her benefit.”In 2010, she was given little shot at winning the governor’s race until Palin visited the state to enthusiastically endorse her. Once again the rough rules of South Carolina politics prevailed. Two men surfaced at the height of the campaign, including a lobbyist who had worked for one of her rivals, claiming to have had affairs with her, while lacking evidence. A fellow lawmaker called her a “raghead.”After his own political career imploded, Gov. Mark Sanford gave Haley a $400,000 donation at a crucial moment in the campaign. “And then she cut me off,” Sanford recalled to Alberta. “This is systematic with Nikki: She cuts off people who have contributed to her success. It’s almost like there’s some weird psychological thing where she needs to pretend it’s self-made.”As governor it was more of the same. She frequently went to war with lawmakers to get her agenda passed. “I have called out legislators from Year 1,” she once declared. “I go to their districts and call them out. I mean, it’s what I’m known for. I put their votes up on Facebook.” One of her great successes as governor was relentlessly lobbying corporations to build their plants in South Carolina. When she left office, the state had 400,000 more jobs than when she entered.She brought the same pummeling manner to her job as U.N. ambassador. All U.S. ambassadors to the United Nations defend Israel, but Haley made it the centerpiece of her job. She waded into a famously anti-Israel institution with fists raised. She was one of the people who made the Trump administration so supportive of the Jewish state. When close allies like Britain and France voted for a resolution condemning the U.S. decision to move its embassy from Tel Aviv to Jerusalem, she did not invite their representatives to a U.S. Mission reception, which is practically war in U.N. terms.Seen through one lens, she is a ruthlessly ambitious person who is happy to bruise people to succeed. Seen from another perspective, she is a brave renegade who fights the old guard to get things done. Seen through a third lens, she is a needlessly competitive personality who makes enemies in profusion. All three viewpoints seem to contain a piece of the truth.A few things need to be said to complicate this picture. First, though she knows how to play hardball, her heart has not been callused over. When nine parishioners at Emanuel A.M.E. Church in Charleston were gunned down by a white supremacist in 2015, she was vulnerable and grieving in public and private. She went to all of the funerals. Her friends worried she was losing a dangerous amount of weight. Mobilized by sadness and anger, she helped persuade more than two-thirds of both houses of the legislature to remove the Confederate flag from the State Capitol grounds, which was an astounding act of political craftsmanship and moral fortitude that even her detractors admire.Second, if she’s often tough as nails, she has generally been tough as tulips about Donald Trump. As The Times’ Sharon LaFraniere has reported, she was not one of the Trump officials who would stand up to try to prevent him from carrying out his more crackpot ideas. “Every time she criticizes me, she uncriticizes me about 15 minutes later,” Trump told Vanity Fair in 2021, which is pretty accurate.I wonder if Haley would be seen as tougher if she were a man. I also wonder if her toughness was forged by being a woman in a conservative, male-dominated state. Maya Angelou offered some wisdom on female toughness in her 1993 book, “Wouldn’t Take Nothing for My Journey Now.” She wrote, “The woman who survives intact and happy must be at once tender and tough. She must have convinced herself, or be in the unending process of convincing herself, that she, her values and her choices are important. In a time and world where males hold sway and control, the pressure upon women to yield their rights of way is tremendous. And it is under those very circumstances that the woman’s toughness must be in evidence.”By this measure, Haley has succeeded amazingly well. But then Angelou added a wrinkle: A woman “will need to prize her tenderness and be able to display it at appropriate times in order to prevent toughness from gaining total authority and to avoid becoming a mirror image of those men who value power above life, and control over love.”There’s often been a wariness around Haley, people worrying she’s mostly about herself. Donald Trump, who really is all about himself, has somehow made himself into the much-beloved tribune of the working class in a way his opponents just haven’t.The Republican Party has come a long way in the last few decades. The party is no longer in the mood for compassionate conservatism or even Ronald Reagan’s sunny optimism. Republicans feel besieged and want a bruiser type who will defend them. In their different ways, Trump and Haley are both products of and architects of the current G.O.P. vibe. Neither Trump nor Haley sits around reading Adam Smith and Edmund Burke. Neither Trump nor Haley has what you would call fully developed philosophies. Neither is conventionally partisan; both made their bones attacking the G.O.P. establishment, not working their way up within it.Mike Pence was too boring to match the party’s current mood. Tim Scott was too nice. Trump and the woman who is now his leading challenger are different versions of a bare-knuckled ethos, and if you look at their records, it’s pretty clear that Haley is actually more effectively tough than Trump. She’s confrontational in pursuit of policy, whereas he is confrontational in pursuit of ratings. She’s a doer; his attention span isn’t long enough to make him an effective executive. If Republicans want someone who will execute their agenda, they should go with her.Unfortunately, Haley’s support in the G.O.P. seems to have a low ceiling. This campaign is about toughness and finding someone who can defend a party that feels under siege, but it’s also about identity and class. Haley is surging, but she is surging mostly among college-educated voters. In general, Haley does better among more educated voters than less, slightly better among men than women, and she does poorly among evangelicals, which these days is as much a nationalist identity category as a religious one.Trump also has an advantage that Haley can’t match. He is reviled by the coastal professional classes. That’s a sacred bond with working-class and rural voters who feel similarly slighted and unseen. The connection between working-class voters and a shady real estate billionaire is a complex psychological phenomenon that historians will have to unpack. But it’s a bond no amount of Nikki Haley toughness can break.Source photograph by Christian Monterrosa, via Getty Images.The Times is committed to publishing a diversity of letters to the editor.
