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.

Trump is winning the favorability contest in South Carolina
In polling conducted since the New Hampshire primary, Trump is viewed favorably by an average of 73 percent of likely South Carolina Republican primary voters, while Haley's average favorability is 51 percent. These numbers are slightly better for the former South Carolina governor than national polling, which, according to 538's tracking, shows 43 percent of Republicans have a favorable opinion of Haley and 81 percent have a favorable opinion of Trump.

South Carolina’s population growth hasn’t shifted its conservative GOP electorate
Spoiler: Whoever wins the Republican primary is probably going to win the state in the general election. Trump beat Biden there by 12 points in 2020, and South Carolina has voted almost exclusively for Republicans in presidential elections since Civil Rights legislation under President Lyndon Johnson flipped most of the South from blue to red. The one exception? The state voted for the Democratic governor of neighboring Georgia, Jimmy Carter, in 1976.
The state reliably votes conservative in other elections too. Its governor, both senators, and six of its seven representatives are Republicans. And many Republican voters there seem fiercely loyal to the former president. Former Rep. Tom Rice, one of ten Republicans who voted to impeach Trump in the House after Jan. 6, was ousted in his midterm primary in 2022.
That said, South Carolina may be changing. Last year it was the fastest-growing state in the country by population growth, driven by the state's growing economy and its relatively affordable cost-of-living. In fact, nearly [10 percent of the potential voting population])) moved to the state since Haley left the governorship in 2017.
While many of those newcomers may have come from the more expensive coasts along the Northeast corridor and California, they don't necessarily seem to be changing the state's GOP electorate, as Haley has struggled to overcome Trump's popularity and name recognition among Republican-leaning new residents. Newcomers or no, Haley's challenges winning over voters in her home state seem not so different from her efforts in the rest of the country.

If the GOP primary race ends tonight, it’ll be the shortest in modern times
Mathematically, Trump can't clinch a delegate majority until the March 12 primaries and caucuses, but he could sew up the nomination earlier if Haley were to suspend her campaign before then. With Haley staring down a potentially sizable defeat in South Carolina, it's possible she could drop out shortly after today's contest. If she did, the 2024 Republican race would rank as the shortest competitive presidential primary since the modern nomination process took shape in the 1970s.
As of today's contest, only four states (plus the U.S. Virgin Islands) have cast ballots. The race ending today — or even after Michigan's primary next week — would beat out the current records for the earliest end date (March 3 in the 2004 Democratic contest) and the lowest number of voting states (19 in the 2000 Democratic race).
An unusually drawn out early voting period likely played a role in winnowing the number of contests candidates could remain viable for: The period from Iowa through South Carolina lasted 41 days, the longest duration from first to last early states since Nevada became an early-voting state in 2008. As a result, Trump could become the presumptive nominee earlier than ever by calendar date and despite barely any states having voted.
Despite that drawn-out early period, the 2024 GOP primary could also be the shortest by the number of days in its competitive period, although that's up for debate. Based on political scientist Caitlin Jewitt's formulation, the 1992 Democratic contest is the shortest ever, having lasted 39 days until former Massachusetts Sen. Paul Tsongas suspended his campaign and left Arkansas Gov. Bill Clinton as the only viable Democratic contender. But the race technically kept going because a candidate with no chance of winning — former California Gov. Jerry Brown — stayed in to push a reform message on issues like campaign finance. If Haley drops out tonight, the 2024 Republican race would last 41 days — a tad longer than the 39-day mark, but also arguably shorter because Brown remained a thorn in Clinton's side beyond it in 1992.

South Carolina primary voters see both candidates as part of the establishment
Majorities of likely South Carolina GOP primary voters said they thought both Trump and Haley are part of the Republican establishment, according to an early February poll from YouGov/CBS News. Seventy-five percent of likely primary voters in the state said Haley is part of the establishment, and 58 percent said the same about Trump. That's not necessarily negative for voters though; in the same survey, 42 percent of likely primary voters said that they thought of the term "Republican establishment" as positive, 33 percent said it was negative, and 25 percent said it was neither positive nor negative.

Haley needs all 50 delegates tonight but might win zero instead
The Republican presidential primary started out in territory pretty friendly to Haley. That changes after today, making the South Carolina primary a sort of last chance for the former Palmetto State governor to prove she actually has a path to the 1,215 delegates necessary to secure the GOP nomination. It looks somewhere between unlikely and impossible that she'll be able to pull that off.
It's all about the numbers. According to the polls, Trump leads Haley by about 30 points among likely Republican primary voters. But his delegate lead is what really matters — and it's likely to be even larger. That's because the South Carolina Republican Party awards its delegates on a winner-takes-all basis. About half the delegates will go to the winner of the statewide vote (almost certainly Trump) and the remainder will go to the winner of each of the state's seven congressional districts. With a 30-point statewide victory, Trump would probably win every district resoundingly; in 2016, the largest difference between Trump's statewide margin (10 points) and his margin in the most anti-Trump county (which he lost by 5 points to Marco Rubio) was only 15 points.
This is all disastrous news for Haley, who needs all 50 delegates from the state to be on track to win the Republican nomination. The competition on and after Super Tuesday will be even tougher. According to the math powering 538's delegate benchmarks, Trump is leading Haley by around 57 points in California and 69 in Texas, the states with the largest delegate hauls on Super Tuesday. Those states also allocate delegates on a winner-takes-all basis, as long as a candidate wins at least 50 percent of the vote.
The primary, in other words, is functionally over. But because Trump has not yet clinched a majority of delegates, Haley's campaign technically has a chance of winning. It's just very, very low.
