Darline Graham Heads to Runoff in South Carolina's Special Senate Race

Darline Graham, appointed to finish the US Senate term of her late brother Lindsey Graham after his death on July 11, 2026, has advanced to a runoff election for the Republican nomination in South Carolina's special Senate primary held August 11. Her opponent in the August 25 runoff had not yet been determined at the time of reporting, with three candidates clustered within a single point of each other in final Trafalgar Group polling for second place The Guardian.

Graham entered the primary backed by the Republican establishment. She held endorsements from Donald Trump, South Carolina Governor Henry McMaster, and Senate Majority Leader John Thune. Her three-week tenure in Washington, she argued, had already produced tangible results: she cited her vote confirming Todd Blanche as attorney general — which she described as the deciding vote — and the passage of a Russia sanctions bill among her accomplishments The Guardian. Sanctions, in this context, are economic penalties imposed by one country on another to pressure a change in behavior; the Russia bill tightened existing measures.

The contest to fill the seat Lindsey Graham held since 2003 drew a crowded field. The late senator had won renomination in the June 9 South Carolina Republican primary with 57% of the vote before his death the following month Ballotpedia. The special primary that followed covered all 46 counties in the state SC Votes, with more than 61,000 early votes cast before Election Day. A court order issued August 4 compelled the South Carolina State Election Commission to add a candidate to the ballots, injecting last-minute uncertainty into an already compressed timeline SC Votes.

The three contenders vying to face Graham in the runoff drew from distinct factions within the state's Republican coalition. Congressman Russell Fry had backing from fellow South Carolina representatives Joe Wilson and Sheri Biggs, but faced criticism for simultaneously running for the Senate and to retain his House seat. Fry's attack advertising amplified a debate comment by Darline Graham favorable to datacenter development and likened her appointment to "DEI" — shorthand for diversity, equity, and inclusion policies, used here by Fry as a pejorative framing of her selection The Guardian.

Congressman Ralph Norman, who has served in Congress since 2017, brought broad support from state legislators and a vote-rich base in the Charlotte suburbs. His campaign emphasized his backing of the Save America Act, a Trump-backed bill imposing federal proof-of-citizenship requirements on states for voter registration The Guardian.

Former Governor Mark Sanford, who served as South Carolina's chief executive between two stints in Congress, campaigned on fiscal stewardship and the increase in federal debt The Guardian. Duke Buckner also appeared on the Republican special primary ballot WWLTV.

The broader context here is the unusual compression of this race. Lindsey Graham's death in mid-July left roughly four weeks before the special primary, an extraordinarily short window for a statewide contest in a state with 46 counties. Graham's appointment by the governor and her immediate Senate service created an incumbency-without-record dynamic that her opponents sought to exploit and she sought to convert into credibility. The Blanche confirmation vote and the Russia sanctions bill gave her concrete legislative markers to cite, but three weeks is a thin record to run on. The runoff on August 25 will test whether institutional endorsements and familial name recognition can carry her past a field drawing from the same Republican electorate that renominated her brother just two months earlier.

The three-way scramble for second place, with Fry, Norman, and Sanford separated by less than a point in Trafalgar's final survey, suggests a fractured anti-Graham vote. If that fragmentation persists into the runoff, the eventual opponent's ability to consolidate the dissenting share of the electorate quickly will be the decisive variable. Fry's line of attack on the "DEI" framing of the appointment, coupled with the datacenter comment, signals an effort to reframe the race around identity and fitness rather than legislative accomplishment. Whether that resonates in a primary electorate that delivered Trump an endorsement sweep across the state's Republican leadership is the open question heading into August 25.

Hand-count audits were conducted in randomly selected precincts following the August 11 primary, and the Election Commission reported unofficial results in real time on election night via scVOTES.gov SC Votes.
