South Carolina's solidly Republican electorate, where Donald Trump carried the state by nearly 18 points in 2024, underpins trader consensus favoring the Republican nominee at 86.5%. Incumbent Darline Graham, appointed after her brother Lindsey Graham's death in July 2026 and confirmed via an August special primary runoff, faces Democrat Annie Andrews. Recent polls show Graham ahead by 8–13 points, consistent with the state's historical patterns and limited Democratic success in Senate contests since the 1990s. The compressed timeline following the vacancy has not altered the race's fundamentals, though general election turnout and any late national shifts remain variables ahead of the November 3 vote.
