Jenny Costa Honeycutt holds a clear edge in the SC-01 House race due to the district’s established Republican lean, reflected in double-digit margins in recent cycles and a Cook Partisan Voting Index around R+6. As an open seat following Nancy Mace’s unsuccessful gubernatorial bid, the contest features Honeycutt, a longtime Charleston County councilwoman and local attorney, against Nancy Lacore, a retired Navy vice admiral who relocated to the area in 2025. Recent September polling shows Honeycutt ahead by double digits among likely voters, while outside Republican groups have increased spending and Lacore benefits from national Democratic support including House Majority PAC reservations. The candidates’ October 7 debate highlighted contrasts on affordability, local experience, and foreign policy, with early voting set to begin October 19 ahead of the November 3 election. Trader consensus aligns with the district’s structural and polling fundamentals.
