The Republican nominee holds a structural edge in South Carolina’s 1st Congressional District due to the seat’s consistent Republican lean in recent cycles and its voter composition along the coastal Charleston area. With incumbent Nancy Mace pursuing higher office, the June 2026 primaries produced Republican Jenny Costa Honeycutt and Democrat Nancy Lacore as nominees following runoffs. Forecasters rate the race Likely Republican, reflecting the district’s partisan baseline and limited crossover support. Recent polling shows the contest remains closer than many other South Carolina House seats, with Democratic performance tied to turnout among coastal and suburban voters. No major late developments have shifted the implied probabilities reflected in current trader consensus.
