The open seat in South Carolina’s 1st Congressional District, vacated by incumbent Nancy Mace’s gubernatorial bid, features Republican nominee Jenny Costa Honeycutt against Democratic nominee Nancy Lacore in the November 3, 2026 general election. The district’s R+6 partisan voter index and consistent Republican performance in recent cycles underpin the 69.5% Republican implied probability, reflecting the seat’s coastal suburban and rural composition that has favored GOP candidates by double-digit margins in most cycles. Primary and runoff results from June 2026 narrowed fields without producing notable cross-party momentum shifts, while Cook Political Report and similar nonpartisan ratings classify the contest as Likely or Solid Republican. Limited general-election polling and absence of major late-cycle developments such as candidate withdrawals or external spending surges have kept trader consensus aligned with the district’s structural Republican advantage, though the 30% Democratic price leaves room for turnout variations or unexpected campaign dynamics before Election Day.
