Readers have questions, including on switching over to another side’s primary, and a quick comment on Swift.A sign that voting is near.Geoff Stellfox/The Gazette, via Associated PressI hope everyone is enjoying the holiday season. We haven’t received many questions about the Republican primary recently, even though the Iowa Caucus is less than three weeks away. But we have gotten a few, and many on other topics, so let’s dive into the mailbox one last time in 2023.Switching parties for a primary?What if some of us former Republicans, now independents or Democrats thanks to Trump, registered as Republicans in order to vote for Nikki Haley in the primary? As a New Jersey voter, it wouldn’t really matter here, because the primaries are usually decided before they get to us. I would much rather see her on the ballot than Trump. Would a push like that do anything? — Nancy DriesMs. Haley trails by 50 points in the national polls, so realistically it’s going to take a lot more than moderate Democrats switching for the race to become competitive.But that doesn’t mean that Democrats and independents won’t play a role. Unlike New Jersey, many states have open primaries where Democrats will be able to vote in the Republican primary without changing their registration at all. It wouldn’t surprise me if Ms. Haley fares especially well in states like those, including South Carolina. She’ll also probably fare well in states where independent voters can participate, like New Hampshire.What about a one-on-one race?When I look at a recent poll of Iowa voters, I see that Trump is at 44 percent with DeSantis and Haley tied at 17 percent. Trump is clearly leading, but there are a lot of voters who are aligning themselves with DeSantis, Haley, Ramaswamy and Christie. And a small number of voters who are undecided.If the Republican field were to narrow down to one candidate who runs against Trump, where do the supporters of those other candidates go? — Steven BrownWhen we surveyed Iowa back in July, we found Donald J. Trump leading Ron DeSantis by 16 points, 55 percent to 39 percent, in a hypothetical one-on-one matchup. Mr. DeSantis won just 51 percent of the voters who didn’t back him or Mr. Trump, and I’d guess the tally is worse for him today, given the trend in the polls since then. I’d also guess it’s worse for Ms. Haley, who would need to win over relatively conservative DeSantis voters.Wrong tack for “wrong track”I’m frustrated with “right track-wrong track” polling — well, maybe more specifically, media coverage of it. It always seems to be presented as poor numbers reflecting badly on the president. But if I’m asked that question, I will say “wrong track” but because of the G.O.P. threat to democracy. Any way to fix that? — Jack CowanTo be honest, Jack, I’ve never been a big fan of the question and we don’t always ask it. That said, I do think it has its place: It’s useful to have a longstanding rough proxy for the national mood, even if it doesn’t yield any insight into the “why.” For that, we have other questions.What are they conserving?The term “conservatives” used to have a specific political meaning. But today what are they conserving? I believe the media needs to adopt more accurate terms to call them, such as right wing populists, or right wing ideologues, or right wing radicals. What they are practicing is no longer true conservatism. Am I wrong? Thank you. — Don NationsI don’t think I agree that “conservative” has always had a consistent, specific and clear political meaning. “Liberal” and “progressive” haven’t had consistent, specific and clear political meanings either.And at least to my mind, today’s conservatives are still true to the most basic definition: a political ideology aimed at conserving a traditional way of life — customs, culture, ideas, institutions, hierarchies, values, beliefs and more.Clearly, some conservatives today see tension between preserving certain traditional institutions — like a democratic republic, which risks empowering those opposed to conservatives — and other conservative aims. But this is not exactly unprecedented in the conservative tradition: Beyond “radical” or “populist” that you offered, terms like reactionary or counterrevolutionary have also been used to describe conservatives who aren’t so conservative in defense of some long-established values.But are they enthusiastic about Trump?Do the polls reflect an increasing popularity for Trump among the young, Black or Hispanic voter sets?I hear a great deal about disaffection toward Biden. But does that mean they are happy or enthusiastic about Trump? — Bryan WatsonIt does not mean they’re happy or enthusiastic about Mr. Trump. In fact, most of the voters who backed President Biden in 2020, but have backed Mr. Trump in recent New York Times/Siena College polling, do not have a favorable view of Mr. Trump at all. They’re also far less likely to say they’ll actually vote, or to have a record of doing so in the past.Who else is out there?Are there any polls that show a Democrat who could beat Trump? Gavin Newsom? — Michele SayreWell, “could” is a pretty loose term! President Biden could beat Mr. Trump, you know. There’s even a perfectly reasonable case he’s still the favorite, despite trailing in polling today.But the polls don’t show any other Democrats beating Mr. Trump, at least outside of their home states. In fairness to them, they’re not especially well known — and, relatively speaking, neither is Mr. Newsom.Hello? Cellphones?If this poll is using the tired old method of calling landline phone numbers, forget it.Especially for young, Black and Hispanic voters, if the pollsters are not using cellphone contacts, they aren’t reaching those voters. None of them has a landline anymore!And, in fact, in my age group (over 65), half or more of the ones I know no longer have a landline. — Robin C. KennedyThe Times/Siena poll is not using the tired old method of calling landline phone numbers. At this point, more than 90 percent of our respondents are reached on their cellphones, and more than 99 percent of our young respondents are reached by cellphone.Taylor Swift effect?I know very little about this person except she’s exceedingly popular with young people and encourages them to vote, apparently Democratic. Could this affect the elections in ’24? If so, is there such a precedent? — Jerry FrankelMy first instinct was to say, “No, of course not,” but …I did not expect her Eras Tour to be the tour of the century, so I’m not sure I’m the best judge of the power of her appeal — which has clearly proven to be extraordinary. I’m not sure her 40-16 favorability rating in a recent NBC/WSJ poll quite does justice her appeal, either.So I asked someone in my household who is far more knowledgeable on the matter whether Ms. Swift could be important in the election and she said: “I think she could. I think she has a ton of power.”Now, even if she does make a difference, it would only be at the margin (right?). But if she did make a marginal difference, it wouldn’t be entirely without precedent. If you have a long memory, you might remember that Oprah Winfrey’s endorsement really might have decided the 2008 Democratic primary in Barack Obama’s favor, though I don’t think a T-Swift endorsement of Mr. Biden would be nearly as symbolic or surprising, given her previous support for Democratic candidates.What are the shares by party?What’s the latest data on the breakdown of Republicans, independents and Democrats? Thanks. — Liz GeorgesIn our last poll, Democrats, Republicans and independents each represented 30 percent of the electorate. I can’t remember getting a clean, 30-30-30 break before (7 percent weren’t sure and 3 percent identified with another party). I thought there was something kind of elegant about it. More
