The June 9 Republican primary for South Carolina’s open 1st Congressional District seat produced no majority winner among the crowded field, advancing Jenny Costa Honeycutt and Mark Smith to the June 23 runoff and leaving other candidates far behind. This fragmented outcome, driven by the open seat after Nancy Mace’s gubernatorial bid, has kept the race tight as traders price the two frontrunners’ relative strengths heading into the final contest. Key factors that could create separation include endorsements from eliminated candidates, last-minute fundraising and turnout efforts among Lowcountry voters, and any shifts in local media coverage or campaign messaging before the runoff vote.
