Darline Graham advanced to the Republican runoff for the U.S. Senate seat in South Carolina following Tuesday's primary results.

The race to fill the vacancy left by the late Sen. Lindsey Graham represents a pivotal moment for the state's GOP leadership and political identity.

Graham secured her spot in the runoff after placing among the top two vote-getters in the Republican primary [1]. The results were projected by CNN's Decision Desk [3]. She will face Rep. Ralph Norman (R-SC) in the final contest to determine the party nominee [2].

South Carolina law requires a runoff when no candidate secures a majority in the initial primary. Both Graham and Norman met the threshold to advance [2]. The runoff election is scheduled for Aug. 25, 2026 [1].

The contest follows the death of Sen. Lindsey Graham, whose seat has become a focal point for national Republican strategy. The primary process sought to identify a replacement capable of maintaining the seat within the party.

While the primary results are now projected, the campaign shifts toward a head-to-head battle between Graham and Norman. The two candidates will spend the coming weeks vying for the support of the Republican base before the Aug. 25 vote [1].

The advancement of Darline Graham suggests a significant influence of name recognition and familial legacy in the South Carolina GOP. By facing Rep. Ralph Norman, the runoff will test whether the electorate prefers the continuity of the Graham legacy or the established legislative record of a sitting congressman.
