Jermaine Johnson's status as a sitting state representative from South Carolina's 80th district has positioned him as the frontrunner in the Democratic primary for governor, set for June 9, 2026, with traders assigning him a 63.5% implied probability. Limited early polling from earlier this year showed him leading amid high undecided rates, reflecting advantages in name recognition and legislative experience within the party. Billy Webster, drawing on prior White House service, and Mullins McLeod, a practicing attorney, trail at 20.0% and 16.5% respectively, while Justin A. Bennett remains further back at 7.0%. With the primary three weeks away, upcoming candidate debates and voter outreach efforts represent the main near-term factors that could shift the field before ballots are cast.
