Mark Smith holds a commanding lead in the South Carolina 1st Congressional District Republican primary as the June 9 contest approaches, buoyed by his record as a sitting state representative, superior fundraising that exceeds $727,000 with substantial cash on hand, and stronger performance in recent candidate forums. The open seat following Nancy Mace’s gubernatorial campaign has drawn a crowded field, yet rivals such as Alex Pelbath, a retired Air Force lieutenant colonel and commercial pilot who has raised over $365,000, trail in early straw polls and local media attention. Other contenders including physician Sam McCown and county officials maintain lower profiles amid the emphasis on fundraising totals, grassroots engagement, and legislative experience that traders view as decisive advantages in this competitive primary environment.
