Jermaine Johnson holds a commanding 76.5% implied probability in trader consensus for the South Carolina Democratic gubernatorial primary nomination, driven by his superior fundraising—recent reports show him raising over $500,000 compared to Mullins McLeod's lower totals—and endorsements from influential figures like Rep. James Clyburn, bolstering his appeal among key Democratic voting blocs in a low-turnout contest. McLeod, at 21%, garners support as a Florence businessman emphasizing economic development but trails in polls and resources. No major developments have emerged in the past 30 days, leaving Johnson's legislative experience and early momentum intact ahead of the June 9, 2026, primary, though new entrants or shifts in party dynamics could alter the race.
