Republican Nancy Mace, who has become one of the GOP’s most unpredictable figures, is running for governor of South Carolina.

Republican Rep. Nancy Mace of South Carolina has launched a campaign for the state’s gubernatorial primary in 2026.

Rep. Nancy Mace (R-SC) is running for governor in South Carolina, she announced Monday. Mace’s declaration comes after months of speculation, sometimes emanating from herself, about whether she would run. She often openly wondered “if I were governor,” or suggested she may be “forced” to run.
