State Senator Jermaine Johnson dominates trader consensus at 76.5% in the South Carolina Democratic gubernatorial primary market, driven by his strong legislative record as House minority leader, superior fundraising—over $500,000 raised early—and endorsements from EMILY's List and key Black PACs, bolstering his appeal in the party's core voting blocs ahead of the June 2026 primary. Mullins McLeod trails at 21% as a self-funding businessman with business credentials but limited political experience and party infrastructure. No major polls have emerged yet, leaving odds reflective of early momentum and incumbency-like advantages in a low-profile primary with few declared challengers; upcoming candidate forums could shift sentiment.
