South Carolina primary 2024: Trump projected to win, Haley vows to stay in the race

What can we take away from Trump's big Palmetto State victory?

Former President Donald Trump has won the South Carolina Republican primary, ABC News projects. It was a swift and embarrassing defeat for former U.N. Ambassador Nikki Haley, who rose to political prominence as South Carolina’s governor. Nevertheless, in her concession speech, Haley vowed to continue her campaign into Super Tuesday on March 5.

Throughout the evening, 538 reporters, analysts and contributors broke down the results as they came in with live updates, analysis and commentary. Read our full live blog below.

Other candidates will be on the ballot, but Haley might have advantage

That's true, Nathaniel. But maybe Haley is hoping that actively campaigning, and still having a campaign apparatus running, will give her an advantage over the other also-rans.

Is Trump is heading for a delegate sweep?

Remember that the primary is ultimately all about the delegates candidates win to vote for them at the RNC in July. In the delegate math tonight, Trump is coming out way ahead. South Carolina awards delegates in two sets: 29 are awarded to the winner of the statewide popular vote (which are all going to Trump tonight) and the remaining 21 are split equally between the remaining 7 congressional districts. According to ABC's delegate projections Trump has already won 38 delegates tonight, with 12 left to assign in 4 more districts. But if Trump is heading for a 30-point margin statewide, it's unlikely Haley will win any of those that remain.

Our delegate benchmarks model had Haley needing all 50 tonight to be on track for the GOP nomination. It is her home state, after all.

You guys never watched “Rowan & Martin’s Laugh-In”?

Am I the only one who uses the term "bet your bippy"??

Don't underestimate the ego factor

Right, so why is Haley sticking around if Trump is the presumptive nominee? We've put together a few hypotheses — spite, in case something happens, sticking it to the man etc — but, as ever with politicians, we cannot discount the possibility that she's in it for her. I keep thinking of Beto O'Rourke's "born to run" comments in the 2020 primary. A lot of politicians think this way!

ICYMI: What’s been happening in the GOP primary

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 caucusit 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.
