Republican Jenny Costa Honeycutt holds a clear edge in the open SC-01 race, an advantage rooted in the district’s post-2022 redistricting that favors Republicans and the departure of incumbent Nancy Mace. Honeycutt, a Charleston County council member and longtime local attorney, benefits from name recognition and recent outside spending by GOP-aligned groups, while Democrat Nancy Lacore, a retired Navy vice admiral new to electoral politics and the area, faces headwinds in a seat rated Likely or Lean Republican by multiple forecasters. A late-September co/efficient poll showed Honeycutt ahead 46-40 percent with third-party and undecided voters remaining, and an early-October debate offered both candidates their first joint platform before early voting begins October 19. The November 3 general election remains the decisive date.
