Mark Smith holds a commanding lead in the South Carolina 1st Congressional District Republican primary because of his five years as a state representative in the House, where he built relationships and legislative experience that resonate with voters seeking continuity. A recent GOP forum straw poll showed him edging out Alex Pelbath, a retired Air Force colonel highlighting his military command record and outsider critique of career politicians. Pelbath, Sam McCown, and Jenny Costa Honeycutt have drawn attention through fundraising and local visibility, while the June 9 primary remains the decisive vote. Traders price these outcomes according to the wisdom of crowds assessing candidate profiles, endorsements, and early campaign momentum in this open-seat contest.
