Core Event – Runoff for Republican Senate Nomination Set for Aug 25, 2026
South Carolina’s special Republican primary for the U.S. Senate seat left no candidate with a majority, sending the top two finishers—Sen. Darline Graham and Rep. Ralph Norman—into a head-to-head runoff scheduled for Aug 25, 2026. Voters who chose a Republican in the primary (or did not vote in either party’s primary) are eligible to cast ballots in the runoff.
Background & Context
The seat became vacant after the death of Sen. Lindsey Graham in early July 2026. Gov. Henry McMaster appointed Graham’s sister, Darline Graham, to serve the remainder of the term. President Donald Trump, who backed Graham in the primary, continues to endorse her for the runoff. The race pits Graham’s appointment-derived incumbency against Norman, a former state representative who placed second in the primary.

- Primary vote share: Decision Desk HQ reported Graham received 32.7 % of the primary vote, while Norman earned 24.6 %.
- Russell Fry’s share: Fitsnews noted Fry captured 19.66 % (66,955 votes), placing third and making his endorsement a potential swing factor.
- Early voting: Begins on Aug 19, 2026, and runs through the weekend before the runoff.

Why It Matters / Impact
The seat is one of the Senate’s most senior Republican positions, and the winner will help determine the chamber’s balance of power heading into the 2026 midterms. Graham’s stance on eliminating the filibuster and her co-sponsorship of the Safeguard American Voter Eligibility Act signal a willingness to pursue procedural reforms, while Norman’s endorsements from established party figures underscore his appeal to the traditional GOP establishment.
