Darline Graham, the appointed incumbent and sister of the late Sen. Lindsey Graham, faces U.S. Rep. Ralph Norman in the August 25 Republican primary runoff to secure the party's nomination for South Carolina's U.S. Senate seat. Graham advanced with roughly 33% in the August 11 special primary after neither candidate reached a majority, benefiting from strong name recognition and an endorsement from President Trump, who has campaigned for her including a recent Myrtle Beach event. A pre-runoff debate drew attention to Graham's limited foreign policy background, which drew audience criticism, while Norman has emphasized his congressional experience and challenged her on issues including campaign funding. Early voting is underway, and the outcome will determine the Republican nominee facing Democrat Annie Andrews in November.
