The open SC-01 seat, vacated after incumbent Nancy Mace’s unsuccessful 2026 gubernatorial bid, favors the Republican nominee Jenny Costa Honeycutt at 69.5% implied probability due to the district’s established Republican lean. The coastal district carries a Cook Partisan Voting Index of R+6 and supported Donald Trump by double-digit margins in 2024, providing structural advantages for GOP candidates in midterm cycles. Recent June primary runoffs selected Honeycutt, a Charleston County councilwoman, over state Rep. Mark Smith on the Republican side and retired Navy Adm. Nancy Lacore over Mac Deford on the Democratic side. A July GQR poll showed Honeycutt leading Lacore 50-48 in a head-to-head matchup, while nonpartisan forecasts rate the race Likely Republican with projected margins of 5-11 points. Democratic super PAC spending and Lacore’s military background keep the seat competitive but have not shifted the overall trader consensus.
