Mark Smith holds the lead in trader consensus for the Republican primary in South Carolina's 1st Congressional District due to his substantial fundraising edge—over $726,000 raised compared to rivals—and his record as a sitting state representative. Recent candidate debates, including one on Hilton Head Island in late May, featured direct challenges to Smith's legislative votes and abstention on redistricting, yet these exchanges have not shifted his frontrunner status ahead of the June 9 vote. Jenny Costa Honeycutt, a Charleston County council member, trails in second place on the strength of her local government experience and emphasis on affordability issues, while Alex Pelbath and others remain further back amid a crowded field that could produce a runoff. Early voting is underway, with no major new endorsements or polling shifts reported in the final days.
