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?

Last Updated: February 24, 2024, 4:55 PM EST

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.

Final thought: If Biden was winning only 60 percent, people would be freaking out

I have become a little obsessed tonight about what we should be expecting Trump to hit in this primary a priori. That is, given Trump is assumed to be the eventual party nominee and almost universally liked in the GOP, should he be winning more than 60 percent in South Carolina?

I already gave my case for answering "no" to that question: Strictly speaking Trump is dominating the delegate count and running ahead of his 2016 vote share in most counties with complete counts this primary cycle. And if you consider that Haley gets a home-state advantage in South Carolina tonight, Trump's adjusted vote share is close to 65 or 70 percent; our delegate benchmarks think Trump should have won 68 percent of the vote based on the demographics of the state alone. That's not the highest number, but it's not the lowest right? Would 65 percent be "good" for Trump? 75 percent? 80?

One counterargument to this centers around how the media has covered historical performances by incumbent presidential candidates. Journalist Jill Lawrence points out that in 1992, Patrick Buchanan challenged incumbent President George H.W. Bush for the GOP nomination and won 40 percent in the New Hampshire primary, holding Bush to 58 percent of the vote. That's an almost identical split to the results from tonight. The New York Times journalist Robin Toner wrote up the results with the headline "BUSH JARRED IN FIRST PRIMARY" and said the result "amounted to a roar of anger" from Republican primary voters.

If Trump was a true incumbent, I imagine the news media would use a similar headline to describe tonight's results in South Carolina. Perhaps our expectations for him are too low, or we're too focused on the broader state of play? Haley said in her concession speech tonight that she will stay in the race indefinitely, so I guess we'll get more data on Super Tuesday — only 10 days from now. The primary lives on!

Final thought: Looking to the suburbs

There are significant differences between primaries and general elections. (If you’re reading this live blog, I’d bet Nathaniel’s next paycheck you already know that.) But I don’t think we should lose sight of where specifically Trump is struggling in South Carolina and in the other early states: metro areas and the suburbs. Tonight, the three counties Haley won happen to be the three counties with the highest educational attainment in the state. We know that one of the primary engines of Democratic success in every cycle since 2016, really, has been improved fortunes among suburban and educated voters. Most Haley voters will end up voting for Trump, yes, but I don’t think it’s insignificant that even as he flexes control over the GOP for eight years running, his problems in the suburbs are still as evident as ever.

Final thought: Haley could actually win delegates tonight

We don't have final results by congressional district (much less overall), but as we can see from a map of the results, Haley is doing better along the coast near Charleston than in much of the rest of South Carolina. That may signal that Haley could carry the 1st Congressional District once all is said and done to win three delegates. That may not seem like much, but Trump swept South Carolina's delegates in 2016, and if Haley is sticking around, winning any delegates has to be part of her strategy to carry on.

Half of the 1st District's population is in Charleston and Beaufort counties, according to Daily Kos Elections — both of which Haley currently lead in. Another 49 percent of the district lies in Berkeley and Dorchester counties, both of which Trump holds an edge in (the remaining 1 percent is in Colleton and Jasper counties). Charleston and Dorchester are both split between the 1st and 6th, so we can't figure out the district-level result based purely on the county-level numbers. So we'll have to see. But Haley's showing in the 1st might be her one bright spot tonight.

Final thought: The primary is over, long live the primaries

You’re right, Nathaniel, this isn’t a real primary. If nothing really dramatic happens, Trump is going to easily walk to the nomination. My silver lining: Super Tuesday marks the start of our downballot primary season, with primary races for Senate in California and Texas, and primaries for House races in five states. So perhaps we’ll have something more competitive to talk about soon.
