Maurice Washington's background as a former Charleston City Council member and Charleston County Republican Party chairman has positioned him as the clear frontrunner in the June 9 Republican primary for South Carolina's 6th Congressional District. Traders assign his nomination an implied 71% probability, reflecting his established local party ties and campaign emphasis on economic opportunity and infrastructure in the district. John Peterson, a banquet supervisor who worked on the 2020 Trump campaign, trails at 8% amid lower name recognition. With the primary five days away and no major recent developments such as debates or endorsements altering the race, the market consensus aligns with the candidates' relative profiles and limited field.
