If Haley truly does drag this out through Super Tuesday, I’m curious what she expects to gain from losing in a couple dozen more states. I get that her motivations are bigger than becoming the nominee at this point, but will such a thorough thumping serve such goals? Only time will tell!

Tonight, Trump became the first non-incumbent Republican in the modern primary era to win all three of Iowa, New Hampshire and South Carolina. Haley has failed to win New Hampshire despite demographics that were practically engineered in a lab to be good for her, and she failed to win South Carolina despite it being her home state. Trump is going to be the nominee; it’s time to start treating the primary as over.

Jacob, I agree that Haley sounded a bit like a third-party candidate tonight, taking on both frontrunners. If any voters were hoping to avoid a Trump vs. Biden rematch, it seems increasingly clear that they won't get their wish. Haley is staying in and attacking both Biden and Trump as two versions of the same thing: old, out of touch and not ready to take the country into the future. She still hasn't fully attacked Trump for his role in Jan. 6 and the court cases against him, which might win her some points with the non-Republican electorate, and it hasn't worked for her so far to try to make the age case against him. I don't think any of this will work, but we'll also have to see how Super Tuesday unfolds, since she seems to be staying in.

If Haley is contemplating a third party bid, she’d have a lot of ground to make up. We’ve seen only two polls testing Haley as an independent, and both show her in the low double digits: SurveyUSA/Charles H. Riggs III has her at 13 percent in a 3-way race against Trump and Biden, with Trump at 45 percent and Biden at 40 percent, and Emerson College has her at 12 percent, with Trump at 42 and Biden at 37. When you throw in Kennedy, West and Stein, she drops to 10 percent in that SurveyUSA poll.

So, if she really wanted to make a go of a third party bid, she’d have to hope something pretty dramatic happened to move voters in her direction. Otherwise, it looks like a third party bid would be DOA.

If you're not quite as election-obsessed as us here at 538, please allow me (a person who willfully chose to spend an evening three weeks into her maternity leave watching the GOP debate) to fill you in on the last few weeks.

At the start of the year, there were still six major candidates competing for the Republican Party nomination. By the end of January, only two remained. In Iowa, Trump came out on top with 51 percent of the vote, followed by DeSantis and Haley. Ramaswamy and Hutchinson both dropped out after the Iowa caucuses (Christie dropped out just before), while DeSantis ended his campaign just before the New Hampshire primary, where Trump defeated Haley 54 percent to 43 percent.

So far, though, Haley has refused to throw in the towel, despite trailing Trump badly in polls.

She also did poorly in two additional contests in early February. In Nevada, where Trump wasn't even on the primary ballot (he was on the ballot for the Nevada GOP caucus … it was a whole thing), she still got only 31 percent, with voters preferring the electoral equivalent of "none of the above." And she lagged behind Trump in the Virgin Islands GOP caucuses, too.

I'll have more in a bit about why Haley might still be running, but suffice to say it's an uphill battle against the former president.
