Jermaine Johnson holds the leading position in South Carolina's Democratic primary for governor, scheduled for June 9, 2026, with a possible runoff on June 23 if no candidate secures a majority. As a three-term state representative from Richland County, Johnson benefits from established legislative visibility, recent polling advantages over rivals, and broader party infrastructure support following the March 30 filing deadline. Mullins McLeod, a Charleston attorney and prior candidate, trails amid lingering effects from a 2025 arrest incident that drew party criticism, while Greenville businessman Billy Webster draws attention for his private-sector background and potential self-funding. Justin A. Bennett remains a distant option. These dynamics reflect trader consensus on Johnson's stronger path in a low-profile primary where name recognition and institutional ties often shape early momentum ahead of the November general election.
