The SC-01 race features an open seat after incumbent Nancy Mace pursued the governorship, leaving Republican Jenny Costa Honeycutt, a Charleston County councilwoman with deep local roots, facing Democrat Nancy Lacore, a retired Navy vice admiral new to electoral politics. The district's post-2022 redistricting and consistent Republican voting patterns underpin trader consensus favoring Honeycutt at 69.5%. A recent October debate and GOP outside spending, including from aligned PACs on mailers and ads, reinforced her positioning, while Democratic groups reserved funds and a Democratic poll showed Lacore narrowly ahead. Early voting begins October 19 ahead of the November 3 general election.
