Maurice Washington leads the SC-06 Republican primary market at 88.5% implied probability, reflecting his established position as former Charleston County Republican Party chair against John Peterson, a local precinct president. The June 9 primary occurs in a district long held by Democrat Jim Clyburn, with recent GOP-led redistricting efforts potentially altering its partisan balance but not directly impacting the Republican contest. No major late developments or endorsements have altered the candidate field or polling signals in the past month, leaving trader consensus anchored on Washington's broader party experience and organizational background. The short timeline to the open primary leaves limited room for shifts absent new announcements or turnout factors among Republican voters.
