Mark Smith maintains a strong lead in the SC-01 Republican primary as the only sitting state representative in the field, backed by superior fundraising, local endorsements, and results from recent GOP forums and straw polls. The June 9 primary decides the nominee to succeed Nancy Mace, who is running for governor, in this solidly Republican Lowcountry district. Challengers including Alex Pelbath, Jenny Costa Honeycutt, Sam McCown, and Jay Byars have focused attacks on Smith’s legislative record during late-May debates, yet none has closed the gap in public attention or resources. Traders reflect this dynamic in current pricing, with Smith favored to secure the nomination amid a crowded field where name recognition and institutional ties typically determine outcomes in South Carolina congressional primaries.
