The Special Republican Primary
South Carolina voters will choose the Republican nominee to fill the U.S. Senate seat left vacant by Sen. Lindsey Graham’s death. The special primary is scheduled for Tuesday, August 11, 2026. Ten GOP candidates are on the ballot, including interim Sen. Darline Graham, the late senator’s sister, and Representatives Russell Fry and Ralph Norman. State law requires a majority; if no one reaches 50 percent, a runoff will be held later in August.
Background & Context
Lindsey Graham died on July 11, 2026. Governor Henry McMaster appointed his sister, Darline Graham, to serve the remainder of the term, and she was sworn in on July 14, 2026. Within days, former President Donald Trump issued a “complete and total endorsement” on Truth Social, pledging that Graham “will never let you down.” The National Republican Senatorial Committee (NRSC) has funded television ads highlighting the endorsement.

Official Statements & Responses
The White House declined to comment.
Criticism & Opposition
Local voters expressed skepticism about Graham’s experience. Analyst David Woodard warned that “Republicans need to be careful—I still think it’s a long shot for a Democrat to win the U.S. Senate in South Carolina, but you don’t want to go into the general election having just pummeled each other so that the winner comes out with tons of negative baggage.”
On-the-Ground Reports
Voters at campaign events highlighted Graham’s decision to remain in Washington. Teresa Castrinos, who drove from Bluffton, said, “She committed to not missing votes or not being there to push forward with those bills,” emphasizing her focus on Senate work.
Conflicting Reports & Gaps
Polling shows divergent leads: Quantus Insights places Graham ahead, while Emerson College and Resonance Media Services show a tighter race. No poll has produced a clear picture of who will secure second place, a crucial factor for any runoff. The legal process for filling Fry’s House seat should he win the Senate nomination remains unsettled, according to state party officials.
What’s Next
If no candidate reaches a majority on August 11, a runoff will be scheduled later in August. Campaigns are expected to intensify outreach as the runoff window approaches, and both Trump’s continued support and the candidates’ ability to connect with voters on the ground will likely shape the final outcome.
