Overview
- The expedited Republican special primary is set for Aug. 11 with a runoff scheduled for Aug. 25 if no candidate wins a majority.
- Interim appointee Darline Graham Nordone is running with President Donald Trump's endorsement after being named to fill her brother Lindsey Graham’s seat.
- Late‑July polls diverge with some surveys showing Nordone ahead while others put Rep. Ralph Norman or a split field in the lead, leaving the race unsettled.
- Republican contenders Rep. Ralph Norman, Rep. Russell Fry, former Gov. Mark Sanford and Nordone are the only consistent double‑digit candidates, raising the odds of vote‑splitting.
- The primary outcome carries national consequence because a Trump‑aligned winner who supports abolishing the filibuster could change Senate procedure and affect GOP legislative strategy.
