Jermaine Johnson, the sitting state representative, leads trader consensus in the South Carolina Democratic primary for governor ahead of the June 9 vote, reflecting his established legislative profile and visibility within the party. Billy Webster, a Greenville businessman who entered the race in March, trails but draws support from his private-sector experience and policy focus on infrastructure and government efficiency. Mullins McLeod, a returning candidate and attorney, and Justin A. Bennett remain distant. Recent activity at the state Democratic convention and a bipartisan candidate forum has kept all major contenders in view, though polling shows substantial undecided Democratic voters that could influence final positioning in the short window before primary day.
