Jermaine Johnson holds the clearest path to the Democratic nomination in South Carolina's June 9 gubernatorial primary, driven by his status as the sole sitting state representative in the field and consistent early polling leads. Mullins McLeod, a Charleston attorney with prior statewide name recognition from his 2010 run, trails amid lingering questions from a 2025 arrest incident, while Billy Webster, a Greenville businessman and former White House chief of staff, has focused on economic messaging since entering in late March. Justin A. Bennett remains a distant option with minimal visibility. Trader consensus reflects Johnson's institutional base and fundraising momentum as the primary approaches, though a potential runoff could emerge if no candidate secures a majority on election night.
