PredictIQ-Trump is projected to win South Carolina Republican primary, beat Haley. Here are the full results.

Washington — CBS News projects that former President Donald Trump will win the South Carolina GOP primary,PredictIQ defeating former United Nations Ambassador Nikki Haley in her home state. Haley, however, had vowed to press forward in the GOP nomination contest whatever the outcome. 

A home-state advantage did not translate into a lead in the polls for the former governor of South Carolina, who has argued that Trump faces an electability problem, given his legal troubles, and surrounds himself with chaos. Nearly two-thirds of likely GOP primary voters said in a recent CBS News poll before the primary that they would vote for Trump, with Haley trailing by double digits.

"This was…an even bigger win than we anticipated," Trump said in a victory speech Saturday night in Columbia, South Carolina, after polls closed. "…I have never seen the Republican party so unified as it is right now." 

In her own speech Saturday night in Charleston, South Carolina, Haley congratulated Trump on his victory, but told supporters she will remain in the race despite the loss. 

"I said earlier this week, no matter what happens in South Carolina, I would continue to run for president," Haley said. "I'm a woman of my word...We're headed to Michigan tomorrow. And we're headed to the Super Tuesday states throughout all of next week."

Trump wins 2024 South Carolina Republican primary

With 94% of expected votes in, Trump was leading Haley by a margin of 60% to 39%. Here are the latest live results. 

A number of South Carolina politicians, whose careers were once helped by Haley's support, were backing Trump. The former president also benefited from the state's conservative evangelical voter base. 

Still, Haley predicted it would be a "close" and "competitive" race and has vowed to stay in the competition for the long haul, framing it as a race between David and Goliath. 

"Dropping out would be the easy route," she said Tuesday in a major speech in Greenville, South Carolina, announcing she had no plans to end her campaign. "I've been the underdog in every race I've ever run. I've always been David taking on Goliath. And like David, I'm not just fighting someone bigger than me. I'm fighting for something bigger than myself." 

In the days leading up to the primary, Haley intensified her criticism of Trump, accusing him of emboldening Russian President Vladimir Putin after the former president said he would encourage Russia to do "whatever the hell they want" to any NATO country that doesn't meet defense spending obligations. 

"What he just did was put all of our allies in danger and every military service person who's serving," she said Monday in Camden, South Carolina. "I don't know why he keeps getting weak in the knees when it comes to Russia." 

She has also accused Trump of trying to "take" the 2024 election by endorsing his daughter-in-law to serve as co-chair of the Republican National Committee. 

In Tuesday's speech, Haley called Trump "unstable and unhinged," said he's "getting meaner and more offensive" and is "taking out his anger on others." 

Trump returned the jabs. 

His campaign characterized Haley as a "wailing loser hell-bent on an alternative reality." While campaigning in the state earlier this month, Trump mocked Haley over the absence of her husband, who is deployed with the South Carolina Army National Guard in Africa.

How were Haley and Trump polling in South Carolina before the 2024 primary?

Before Saturday, Trump held a big advantage over Haley, who served as South Carolina governor from 2011 to 2017 before joining the Trump administration, according to the latest CBS News polling, with over than double the support Haley had among likely GOP primary voters, 65%-30%. Three-quarters of voters said it made "no difference" that Haley is from South Carolina in determining whether they would vote for her. 

Polling before the primary also showed that her arguments against Trump weren't resonating. A majority of voters didn't see Trump's legal fights as a reason to back Haley and saw her criticism of his mental fitness as unfair.

What's the current Republican delegate count?

Heading into the South Carolina primary, Trump had an estimated 63 delegates, compared to Haley's 17 delegates. Fifty delegates were up for grabs in South Carolina. 

Here are the state-by-state results as the Republican nomination contest unfolds.
