Darline Graham won South Carolina’s Republican Senate runoff on August 25, defeating U.S. Rep. Ralph Norman with 52.5% of the vote to advance to November’s general election, where she will seek a full six-year term to replace her late brother, Lindsey Graham.
Graham was appointed by Gov. Henry McMaster on July 13 to fill the remainder of her brother’s term after Lindsey Graham died on July 11 from an aortic dissection caused by cardiovascular disease. The special primary runoff followed an August 11 initial contest in which Graham led a 10-candidate field with 33% of the vote, with Norman finishing second at 24%, triggering the two-week runoff.
President Donald Trump played a decisive role in Graham’s victory. He encouraged her to enter the race for a full term before she had officially announced her candidacy, endorsed her publicly, and campaigned for her in Myrtle Beach on Friday, August 23. Trump’s super PAC, MAGA Inc., spent more than $800,000 on voter calls and text messages supporting Graham in the final stretch.
Graham is a political newcomer without elected office experience. She spent decades in public service, serving as head of South Carolina’s Commission for the Blind and holding prior positions with Clemson University and the state Department of Employment and Workforce. During her brief campaign, she repeatedly stressed her intent to support Trump’s policy positions and her co-sponsorship of a voting bill that has become a key priority for the president.
Norman, a five-term congressman and member of the hard-right House Freedom Caucus, campaigned on his legislative experience and willingness to take unpopular stances. He secured endorsements from Sens. Rick Scott of Florida and Mike Lee of Utah, as well as former South Carolina Sen. Jim DeMint. Norman spent more than $1 million of his own fortune on the campaign in the final week alone. At his election-night watch party, Norman acknowledged his loss but criticized Graham for accepting outside PAC money and Trump for intervening in the race.
Graham stumbled during the single runoff debate when asked about U.S. national security interests in Taiwan and the South China Sea—a signature issue for her late brother. She struggled to answer directly and admitted “national security is not my thing” and “I’m not that informed on national security.” Norman responded by calling Taiwan “a definite ally” and applauding Trump for “enabling Taiwan to defend themselves against China.” Some voters cited her answer as evidence of insufficient preparation, though others dismissed concerns as media spin.
Graham will face Democratic nominee Annie Andrews, a Charleston-area pediatrician, in November. No Democrat has won a U.S. Senate seat in South Carolina in decades. When Lindsey Graham last ran in 2020, he defeated his Democratic opponent by 10 percentage points in what was then the most expensive Senate race in state history.
