Mark Smith leads the Republican primary for South Carolina’s 1st Congressional District with trader consensus at 54 percent, reflecting his position as a sitting state representative and top fundraiser among the crowded field of ten candidates. Recent debates, including the May 29 event on Hilton Head, highlighted differences on issues such as inflation, redistricting, and local infrastructure, with Smith defending his legislative record while facing questions from rivals. Jenny Costa Honeycutt, a Charleston County council member at 27 percent, draws support through emphasis on affordability and local government experience. The June 9 primary occurs in an open seat previously held by Nancy Mace, with the possibility of a runoff if no candidate reaches a majority. Other contenders trail due to lower name recognition and fundraising totals.
