**Darline Graham Nordone holds a strong lead in trader consensus for the South Carolina Republican special primary runoff on August 25, 2026, following the death of Sen. Lindsey Graham in July.** As his sister and the appointed interim senator, she benefits from immediate name recognition, party infrastructure support, and an early endorsement from President Trump. She finished first in the August 11 primary but fell short of a majority, advancing alongside Rep. Ralph Norman. Norman has positioned himself as the anti-establishment alternative, emphasizing differences on experience, campaign funding, and policy during the recent debate, while seeking to attract voters skeptical of the Graham family legacy. Other filed candidates, including several sitting members of Congress and former officials, registered minimal support and did not advance. The compressed timeline, with the runoff just days away, has concentrated attention on these two contenders. Current pricing reflects the market's assessment of Nordone's advantages in the final head-to-head contest, while leaving room for shifts based on turnout in the remaining days.
