South Carolina holds both a U.S. Senate race and an open governorship in 2026, on the ballot November 3, 2026, in a reliably Republican state where the primaries often decide the outcome. Here's a nonpartisan guide.
What's on the 2026 ballot in South Carolina?
The U.S. Senate seat held by Republican Lindsey Graham is up for reelection. The governorship is open, with Republican incumbent Henry McMaster term-limited, drawing a competitive Republican field. Below them: all of South Carolina's U.S. House seats, state offices, legislative races, and local contests.
What makes South Carolina's races matter?
South Carolina votes reliably Republican in federal and statewide races, which means the Republican primaries, for the open governorship especially, often decide the officeholder. Those primaries are small, engaged, high-information electorates where a strong texting program is unusually effective. The state also holds an early, closely-watched presidential primary tradition that keeps its Republican electorate especially organized and attentive.
Why turnout decides South Carolina
Because safe-seat primaries decide much of the ballot, mobilizing a small primary electorate carries outsized weight, and a midterm lowers turnout further. South Carolina's early and mail voting spreads the work across weeks, and its mix of metro areas, coastal communities, and rural counties makes reaching a varied electorate the task.
