The June 9 primary results in South Carolina’s 1st Congressional District produced no majority winner among the crowded Republican field, advancing Charleston County Councilwoman Jenny Costa Honeycutt and state Representative Mark Smith to the June 23 runoff under state rules. Honeycutt led initial vote tallies at roughly 22 percent while Smith followed at 18 percent, with the remainder split among more than a dozen other candidates including Sam McCown and Alex Pelbath. This fragmented outcome has kept the runoff contest tightly matched in trader assessments, as both finalists draw from overlapping Lowcountry conservative bases with limited time for differentiation before the second round. Scheduled debates, local endorsements, and turnout patterns in key counties such as Charleston and Beaufort could still shift momentum ahead of resolution.
