Haley said tonight that she's staying in the race, with an eye on the Feb. 24 GOP primary in her home state of South Carolina. Besides the caucuses in the U.S. Virgin Islands on Feb. 8, there won't be another Trump-Haley matchup until South Carolina because Haley didn't file for Nevada's Feb. 8 caucuses, which Trump was expected to easily win even before everyone else dropped out besides Haley. I'd make it a 50-50 proposition whether she stays in until South Carolina, however.

With the Palmetto State up next, I can see why Haley would like to stick around: Maybe she can win over voters in her home state, or something else could happen in the race to cause Trump's position to deteriorate. For instance, he's made some garbled, confused statements in recent days, including appearing to confuse Haley for Nancy Pelosi when talking about the Jan. 6 attack on the U.S. Capitol. Yet Haley also has to keep raising money to keep her campaign alive. That could be a challenge as GOP donors increasingly look ahead to the general election and her chances of defeating Trump look to be between slim and none. Moreover, if her position in South Carolina doesn't improve in the next couple weeks, she may not want to risk taking a big loss on her home turf.

I think Haley will stay in through South Carolina for the reason Monica stated — to consolidate the non-Trump primary vote, however small. Haley seems to be bolder in her attacks on Trump as time goes on (like drawing attention to his mental fitness as she did tonight). That also tells me she isn't ready to drop out.

I'm not sure. In earlier live blogs and chats, we've wondered if one candidate could consolidate the non-Trump vote. It looks like Haley has done that in New Hampshire. Thirty-five percent of New Hampshire voters identified with the MAGA movement, according to exit polls, and Haley won 66 percent of those who were not part of the movement. If she wants to prove that there is a contingent of Republicans in the country that do not want a second Trump term, she could stay in and hope that something happens or she gains actual ... wait for it ... momentum. She said in her speech that it's not over, and that's technically true.

Hmm, I dunno, Jacob. I kinda think Haley might pull a DeSantis: She thinks she can muddle through now, but in a couple weeks, if she hasn’t made any dent in Trump’s lead in South Carolina, she may decide it’s fruitless and pull the plug. She may want to avoid the embarrassment of losing in her home state. In any event, I am quite sure that Haley will drop out if she loses South Carolina outright — meaning I bet Super Tuesday won’t even be relevant this year.

At around 4:30 p.m., Americans for Prosperity Regional Director Greg Moore said on X (formerly Twitter) that he'd heard from sources in the New Hampshire secretary of state office that towns around the state had gone through more than 80 percent of GOP primary ballots available statewide, and that some towns were calling to ask for more to avoid running out. Polls in much of the state closed at 7 p.m Eastern, but a few places are open until 8 p.m.

Now, the Koch-affiliated AFP endorsed Haley to much fanfare earlier this cycle, so high turnout certainly would make Haley supporters feel hopeful about the number of independent voters taking part in the primary, who generally are more likely to support Haley than Trump. Still, ABC News's current total expected vote total in New Hampshire is 330,000 votes. Although that figure may change as the night wears on — it could go higher or lower — that many votes would represent nearly 30 percent of the state's entire voting-eligible population — that is, anyone who is eligible to register and vote. A turnout rate at that mark would be on par with the highest turnout in the state's modern history, which was the highly-competitive 2008 Democratic presidential primary.
