Core Event
On August 11, 2026, Darline Graham—appointed interim senator after her brother Lindsey Graham’s death on July 11, 2026—finished first in the Republican special primary for South Carolina’s U.S. Senate seat with roughly 33 percent of the vote. Rep. Ralph Norman placed second with about 24 percent. Because no candidate reached a majority, a runoff between Graham and Norman is scheduled for August 25, 2026.
Background & Context
Lindsey Graham, who had won the June 9, 2026 Republican primary for his fifth Senate term, died unexpectedly from an aortic tear on July 11, 2026. Governor Henry McMaster appointed his sister, Darline Graham, on July 13, 2026 to serve the remainder of the term, which ends in January 2027. The special election timeline was compressed: filing opened July 21–28, 2026, the primary was held August 11, 2026, and the runoff is set for August 25, 2026.
Data & Statistics
- Ten Republicans contested the primary.
- With about 80 percent of precincts reported, the Associated Press counted Darline Graham at 32.6 percent, Ralph Norman at just over 24 percent, Russell Fry around 20 percent, Mark Sanford near 15 percent, and businessman Mark Lynch roughly 7 percent (Reuters, NBC News, AP).
- The Republican nominee is widely expected to win the November general election against Democrat Annie Andrews, a pediatrician, as South Carolina has not elected a Democrat to the Senate in decades.
Official Statements & Responses
- Donald Trump: “She looks so nice, but she’s actually tough and strong, and she’s the perfect person to carry on Lindsey’s legacy. She has my complete and total endorsement … right from the beginning. She fully supports the Trump agenda and will help us achieve our mission.”
- Darline Graham: “I decided to answer the call to serve because South Carolina and President Trump need a leader who’s tough, principled and will fight to advance our conservative values in Washington.”
- Ralph Norman: “The Senate is the body where good bills die.”
- Mark Sanford: “I got into this race because I believe our nation is at a financial tipping point.”
Criticism & Opposition
On-the-Ground Reports
- Voters in Lexington noted Graham’s demanding campaign schedule but praised her stamina.
- Longtime activist Eaddy Roe Willard highlighted the personal nature of South Carolina politics: “You know, South Carolina politics is very local.”
Conflicting Reports & Gaps
- Vote percentages differ slightly across outlets (AP’s 32.6 percent vs. NBC News’s “about 33 percent”), reflecting rounding rather than substantive disagreement.
- Polls on the second-place finishers vary; Norman, Fry, and Sanford are within a 1-2-point margin, leaving the exact runoff opponent uncertain until the final count.
What’s Next
The runoff between Darline Graham and Ralph Norman will take place on August 25, 2026. The victor will appear on the November ballot as the Republican challenger to Democrat Annie Andrews.
