Mallory Dittmer maintains a strong lead in the South Carolina 5th Congressional District Democratic primary due to her earlier entry into the race, higher fundraising totals, and broader name recognition among party activists and local advocates. Andrew Clough, a Rock Hill airline worker emphasizing working-class issues, remains a distant challenger in this open-seat contest with no incumbent. Early voting began on May 26 ahead of the June 9 primary date, giving Dittmer additional time to consolidate support through endorsements and outreach. The two-candidate field has produced limited late shifts, with trader consensus reflecting Dittmer's structural advantages in a low-profile primary where turnout patterns among Democratic voters will determine the nominee.
