The open SC-01 seat, vacated by Rep. Nancy Mace's bid for governor, carries a Solid Republican rating from Cook Political Report with an R+8 partisan voter index, anchoring trader consensus at 72% for a GOP winner amid the district's historical dominance. Former Gov. Mark Sanford's withdrawal on April 30 has prompted speculation of primary consolidation ahead of the June 9 primaries, where a crowded 10-candidate Republican field showed no dominant frontrunner in an April 17 forum straw poll led by Mark Smith at 34%. Democrats hold 26% implied probability following the DCCC's February target designation and solid Q1 fundraising for Nancy Lacore, though no public general election polls indicate a competitive contest.
