Maurice Washington leads the SC-06 Republican primary market at 70.5% due to his background as former Charleston County Republican Party chairman and city council member, giving him greater name recognition and organizational ties compared to John Peterson, a precinct president and banquet supervisor positioned at 8%. The race simplified after South Carolina's redistricting effort stalled, leaving these two candidates on the June 9 ballot with no other Republican contenders. Trader consensus reflects Washington's established party role and public campaign emphasis on district economic concerns, while Peterson's lower profile has limited momentum in the short window before primary voting. No major recent endorsements or shifts have altered the positioning ahead of the open primary.
