Darline Graham Nordone leads the South Carolina Republican Senate special primary runoff with strong trader consensus, reflecting her position as the appointed incumbent following Lindsey Graham’s death in July 2026. In the August 11 special primary, she captured the top spot at roughly 33 percent, advancing against Ralph Norman, who placed second. Her family tie to the late senator, combined with an early gubernatorial appointment and reported Trump endorsement, has consolidated support among Republican voters in the compressed three-week campaign. Norman, a sitting congressman, trails significantly in market pricing ahead of the August 25 runoff, as does the broader field of other filed candidates. The outcome hinges on turnout in the final days before the runoff resolves the nominee for the November general election.
