Rep. Ralph Norman (R-SC) and Darline Graham have advanced to the Republican runoff election for a U.S. Senate seat in South Carolina.
The contest determines who will fill the vacancy left after the death of Sen. Lindsey Graham. The seat remains a critical point of contention within the state's Republican party as they seek a successor for the late senator.
The primary election took place on Tuesday, Aug. 11, 2026 [1]. Following the results, Norman and Graham emerged as the top two candidates, necessitating a second round of voting to decide the party nominee.
Graham is the sister of the late Sen. Lindsey Graham. Her presence in the race brings a familial connection to the legacy of the previous officeholder, while Norman brings experience from the House of Representatives.
The runoff election is scheduled for Aug. 25, 2026 [2]. This condensed timeline leaves the candidates with less than two weeks to consolidate support and appeal to voters who backed other candidates in the primary.
South Carolina law requires a majority for victory in primary elections. Because neither candidate secured more than 50 percent of the vote on Aug. 11 [1], the runoff serves as the final deciding factor for the GOP nomination.
Norman spoke to supporters following the announcement of the results. The race now centers on the ideological and personal differences between the sitting representative and the sister of the former senator.
“The runoff determines who will fill the U.S. Senate seat left vacant after the death of Sen. Lindsey Graham.”
The runoff creates a direct clash between established legislative experience and familial political legacy. With the election occurring so shortly after the primary, the outcome will likely depend on which candidate can more effectively absorb the support of eliminated primary challengers in a high-turnout environment.
