Trump-backed Darline Graham wins South Carolina Senate runoff, will face Democrat in November

Sen. Darline Graham won the Republican nomination for South Carolina's open U.S. Senate seat on Tuesday, defeating Rep. Ralph Norman in a runoff that capped a six-week sprint to succeed her late brother, longtime Sen. Lindsey Graham, who died in July of an aortic dissection at age 71.

With all precincts reporting, Graham had captured roughly 52.5% of the vote to Norman's 47.5%, according to results confirmed by NBC News. She now advances to a November general election against Democratic nominee Dr. Annie Andrews, a Charleston pediatrician who cleared her own primary field in June. The South Carolina Election Commission is conducting hand-count audits of the runoff results as part of its standard post-election verification process.

Graham, a political newcomer with no prior elected experience, was appointed by South Carolina's governor to serve out the remainder of her brother's term after his death. She quickly drew a swift endorsement from President Trump, who campaigned for her in Myrtle Beach and whose political operation, MAGA Inc., disclosed spending more than $827,000 to boost her candidacy, according to CNN's coverage of the race.

A late surge past a sitting congressman

Norman, a five-term House member from the state's 5th District known for hardline conservative positions, had shown late momentum in the runoff campaign and was viewed by some party strategists as the more battle-tested option. But Graham's connection to her brother's legacy, combined with Trump's backing, proved decisive in a state where the president remains broadly popular.

"South Carolina is truly Trump country," Graham told supporters at her victory party Tuesday night, a line widely read as both a tribute to the president's coattails and a signal of how she intends to govern if elected in her own right.

South Carolina has not elected a Democrat to statewide federal office in years and backed Trump by roughly 18 points in 2024, making it a steep climb for Andrews, who ran unsuccessfully against Lindsey Graham for the same seat in 2020 before building name recognition that helped clear her a path through this year's Democratic primary. Local coverage of the runoff, including from Live 5 News in Charleston, noted turnout was heavier in upstate counties that had favored Norman in the initial primary, suggesting Graham's coalition drew more broadly from across the state in the runoff.

Lindsey Graham had represented South Carolina in the Senate since 2003 and chaired the Judiciary Committee before his death in July, a loss that reshaped the state's political calendar and forced both parties into an accelerated nomination process over the following weeks. Democratic strategists argue the general election could tighten if the president's national approval ratings continue to soften, and they point to Andrews' fundraising as a reason the contest may draw outside money. Graham is expected to be sworn in to a full term if she prevails in November, continuing to hold the seat in the interim under her gubernatorial appointment. Her rapid rise from private citizen to Senate nominee within seven weeks of her appointment has drawn comparisons to other family successions in Congress, though South Carolina Republican officials have described her candidacy as earned on its own merits rather than inherited.
