State Representative Jermaine Johnson leads the June 9 Democratic primary for South Carolina governor with strong trader consensus at 70 percent, ahead of businessman Billy Webster at 27 percent. Johnson’s established legislative record, active statewide campaigning, and recent appearances at the South Carolina Democratic Party convention have built visibility among primary voters. Webster, who entered the race later, draws support through business experience and policy emphasis on infrastructure and healthcare, yet trails in available polling. Mullins McLeod and Justin A. Bennett remain distant factors with limited name recognition. High undecided shares in May surveys suggest room for shifts before election day, but Johnson’s institutional position and consistent outreach currently anchor market pricing.
