Worth remembering that in 2020, the person who ultimately won the Democratic primary finished ... checks notes ... fifth in New Hampshire.

In her speech, Haley mentioned polling showing her beating Joe Biden while Trump does not. Can you trust those findings? When I analyzed the same question in 2016, I found that voters who said they'd back one candidate but not another during the primary often mean it during the general.

This race is unprecedented in recent history, with a twice-impeached president seeking to return to the White House. Given that, and given that so many delegates are still outstanding, I can see why Haley wouldn't want to throw in the towel quite as quickly as a candidate might in prior years.

I agree with Geoffrey on this one. While she claims to be in it for the long haul, the truth is that Haley has plenty of time to think about her decision. With a month till South Carolina votes, she can take a beat to see if the polls change or the money dries up. If she finds her position deteriorating, there's always time to make an exit before South Carolina starts voting, and I don't know that there would be much difference, other than possibly some short-term embarrassment, between dropping out now or next week.

New Hampshire is one of the least religious states in the country. That might help explain why Trump’s closest competitor, Haley, has closed in on his lead a bit there: He’s at 54 percent to her 36 percent. While in 2016, evangelical Christians and regular churchgoers were reluctant to throw their support behind Trump, this key Republican voting bloc is now his solid base. And they’re missing in this first-in-the-nation primary.

In Iowa last week, Trump improved on his 2016 caucuses performance by 35 points in the most evangelical areas of the state, according to a Washington Post analysis. That’s just the latest evidence that evangelical voters are his to lose. In the 2020 general election, he won 59 percent of voters who attend church at least monthly, according to a Pew Research Center analysis. More than that, Trump moved many of his voters to identify as evangelical Christian, regardless of their church attendance habits.

Evangelicals remain one of the most motivated, active parts of the Republican Party nationwide, and, without that, Trump’s campaign might be missing a little steam. In addition to being less religious, New Hampshire residents have other identity markers that pull them further from Trump’s base. It’s one of the most educated states in the country, and has had an active Libertarian Party. In this respect, New Hampshire Republicans are a bit different from their fellow party members in other states. All of these factors might be giving Haley a small opening, but Trump is still favored to win.

Looking beyond that toward November, New Hampshire has voted for the Democratic candidate in every election save one since 1992. So while the eventual Republican nominee will have a shot, the less religious nature of New Hampshire might be a sign that the state is simply becoming more solidly Democratic like its New England neighbors, at least when it comes to presidential elections.
