South Carolina GOP runoff tests Trump’s 2028 influence
South Carolina Republicans head to a runoff Tuesday to replace a late senator, with President Trump's endorsement at stake.

The update
South Carolina Republicans will decide Tuesday who will replace the late Sen. Lindsey Graham on the ballot in November’s midterm election. The race is a runoff between Sen. Darline Graham, the late senator’s sister, and Rep. Ralph Norman. The two candidates were the top two vote-getters in a special primary election on Aug. 11. Darline Graham, who has no prior experience in elected office, has focused on domestic issues during the abbreviated campaign. Her lack of preparedness in foreign policy has raised questions about her candidacy for the full term.
Why it matters
The outcome is a test of President Trump’s influence in the GOP. Trump has endorsed Darline Graham, and her ability to secure the nomination could signal how effectively his support translates into electoral victories. The race also highlights the challenges of replacing a high-profile senator mid-term, particularly when the successor lacks political experience.
What to watch
Watch how the campaign unfolds in the final days leading up to the runoff. The focus will likely remain on domestic issues like healthcare affordability, as Graham has emphasized these topics over national security. Additionally, the race could reveal whether the GOP can unify behind a candidate in a high-profile runoff.
