Trump endorsed Darline Graham over Rep. Ralph Norman. Will Graham win South Carolina's Republican Senate runoff Aug 25?
75% of users predicted YES — the community got this one right. 24 predictions cast.
Darline Graham defeated Rep. Ralph Norman in South Carolina's Republican Senate primary runoff on Aug. 25, 2026, winning by roughly 52% to 48% with nearly all votes counted. The special election was called after the death of Sen. Lindsey Graham, Darline Graham's brother, six weeks earlier; she entered the race as a political newcomer recruited and endorsed by President Trump, who campaigned for her ahead of the runoff.
Norman, a longtime U.S. House member, had built support among state Republican officials but could not overcome Trump's late, aggressive push on Graham's behalf, including his direct campaigning in the runoff's final weeks. Graham's win secures her spot on the November ballot for the remainder of the Senate term, where she will face Democratic nominee Annie Andrews, a pediatrician, in the heavily Republican state.
The community predicted the outcome correctly: 75% of forecasters expected Graham to win, and she did. National coverage framed the result as a notable win for Trump's endorsement record after setbacks in several other 2026 primary contests.
