COLUMBIA, S.C. (AP) — South Carolina Attorney General Alan Wilson won a runoff election on Tuesday, swiftly routing the candidate initially endorsed by President Donald Trump to be the Republican nominee for governor.

Wilson defeated Lt. Gov. Pamela Evette, whom Trump backed in the closing days of the primary campaign. The president later said he supported both candidates, hedging his bets in the race after his candidates for governor lost in Iowa and Georgia earlier this month.

Wilson, the son of longtime U.S. Rep. Joe Wilson, has served as the state's top prosecutor since 2011. His victory sets up a November general contest with state Rep. Jermaine Johnson, who won the Democratic nomination outright two weeks ago.

As news spread of Wilson's win, scattered whoops went up around the downtown Columbia ballroom, where supporters had only begun to fill in for his Election Night party.

Trump at the center of the campaign

The Republican primary to succeed Gov. Henry McMaster, who is term-limited, largely centered around candidates' proximity to Trump, with nearly all of the contenders expressing hope of securing his endorsement.

That achievement initially went to Evette, 58, who has served alongside McMaster for two terms, in the primary's closing days. Long before that, Evette often featured photos and video of herself with the president in campaign ads and other materials. She also hired a campaign team that includes Trump's longtime pollster Tony Fabrizio.

But as Wilson seemed to gain momentum heading into the runoff, Trump on Friday said he was endorsing both candidates, throwing a curveball to voters looking to the president for guidance.

Wilson, 52, also boasted support from sheriffs and solicitors across the state, law enforcement officials with whom he works often as South Carolina's top prosecutor.

Immediately following Trump's double endorsement on Friday, Wilson began boasting about it, too. Moments after Trump posted on social media, South Carolina Sen. Tim Scott said he was also supporting Wilson. A person familiar with the senator's thinking but not authorized to speak publicly said Scott had been making calls in support of Wilson, helping raise money and lobbying Trump to back him as well.

On Monday, Sen. Ted Cruz, another Wilson backer, came to South Carolina to stump for him.

Other primary candidates who failed to make the runoff, including U.S. Reps. Nancy Mace and Ralph Norman, endorsed Wilson. Although Mace had fiercely feuded with Wilson, he said they had "buried the hatchet."

Republican runoff was South Carolina primaries' last major contest

The only runoff debate between Wilson and Evette was heated. Because each was given time to issue a rebuttal whenever their name was mentioned, the debate's first half-hour swiftly devolved into a ping-ponging, back-and-forth over allegations of mudslinging and taxpayer-funded salary increases. The audience provided a soundtrack of thunderous jeers and hoots.

While Democrats also had multiple candidates running in some primary contests earlier this month, they're not dealing with runoffs in the top races.

State Rep. Jermaine Johnson, seen a rising star among South Carolina Democrats, defeated two other hopefuls to win his party's gubernatorial nomination outright,

And Charleston physician Annie Andrews also cleared the Democratic field in her challenge to Graham.

Winning statewide in November remains tall order for Democrats

While South Carolina Democrats hope their primary momentum helps propel them to general election wins, they have lots of ground to make up on that front.

McMaster notched double-digit victories in 2018 and 2022, defeating Democrat Joe Cunningham by nearly 18 percentage points. Democrats haven't won a governor's race in the state since 1998.

As for U.S. Senate seats, no Democrat has won one of those here in decades either. When he last ran in 2020, Graham defeated his Democratic opponent, Jaime Harrison, by a 10 percentage point margin. That contest was the most expensive in state history, and among the country's most expensive congressional races ever.

The last time a Democrat won any statewide-elected seat in South Carolina was 2006. And in recent history, Republicans have typically taken statewide seats in the state by double-digit margins.
