South Carolina’s solidly Republican electorate and voting patterns continue to anchor trader consensus around an 89% probability for the eventual Republican nominee in the November 2026 Senate contest. The death of incumbent Lindsey Graham after his June primary victory triggered a special August 11 primary and August 25 runoff between interim appointee Darline Graham and Rep. Ralph Norman, with President Trump’s endorsement of Darline Graham shaping the field. Democratic nominee Annie Andrews, a pediatrician who won her June primary, faces structural headwinds in a state where Republicans have held the seat for decades. Recent polling and fundraising data show no competitive crossover support or turnout shifts capable of altering the baseline partisan advantage ahead of the general election.
