The open SC-01 seat, vacated by retiring Republican Nancy Mace, features Republican Jenny Costa Honeycutt against Democrat Nancy Lacore in a district with a Cook PVI leaning Republican by six points. Recent polls, including a late September co/efficient survey showing Honeycutt at 46% to Lacore’s 40%, combined with forecaster shifts to Lean Republican ratings from Cook and Inside Elections in mid-October, reflect a narrow contest sustained by Lacore’s fundraising advantage and attacks on Honeycutt’s local development positions alongside strong outside spending from both parties’ congressional committees. The closely matched trader pricing across narrow margin buckets aligns with historical base rates for this swing-leaning coastal district and the limited time remaining before November 3 voting, where turnout among suburban voters or late campaign events could widen the final spread.
