Core Event
On August 25, 2026 (scheduled), South Carolina voters will choose the Republican nominee for the U.S. Senate seat left vacant by Sen. Lindsey Graham’s death. The runoff pits appointed Sen. Darline Graham against Rep. Ralph Norman after neither secured a majority in the August 11, 2026 special Republican primary, where Graham led with roughly one-third of the vote and Norman placed second.
Background & Context
Sen. Lindsey Graham died on July 11, 2026. Gov. Henry McMaster appointed his sister, Darline Graham, to finish the term and run for a full seat. Former President Donald Trump endorsed her, calling the endorsement “complete and total.” Ten Republicans entered the race, including Rep. Russell Fry, former Gov. Mark Sanford, and businessman Mark Lynch. The filing window (July 21-28) and the need for a primary before the November general election created an accelerated campaign cycle.

Why It Matters / Impact
The winner will appear on the November 3, 2026 ballot in a state that has not elected a Democratic senator since 1998, making the race pivotal for the GOP’s Senate numbers. The contest also gauges Trump’s sway in South Carolina and will determine whether the Graham family’s Senate legacy, ongoing since 2003, continues.
Official Statements & Responses
Trump reiterated his “complete and total endorsement” in a July 17 post, urging support for Graham. Norman emphasized his fiscal-conservative record and said “faith, family and freedom” are needed to “tip the right way” for the state.
Criticism & Opposition
Republican voters questioned Graham’s lack of elected experience. Voter George Mitford remarked, “I just thought he’d probably had more experience in this than she would have had,” referring to Norman’s longer career. Critics also noted Graham’s brief tenure and limited legislative record as potential liabilities.
Conflicting Reports & Gaps
Vote-share figures vary slightly (Graham 32.7 % vs. 32.74 %; Norman 24.6 % vs. 24.65 %). No source provides a definitive count of undecided voters, leaving uncertainty about the runoff’s swing potential.
What’s Next
The runoff is set for August 25, 2026 with early voting beginning mid-August. The victor will become the Republican nominee and face Democrat Dr. Annie Andrews in the November 3, 2026 general election. Campaigns will intensify over the next two weeks as both candidates target counties they missed in the primary.
