South Carolina Republicans are moving quickly to fill the U.S. Senate vacancy left by the sudden death of Sen. Lindsey Graham, triggering an accelerated election schedule as potential candidates begin weighing bids for one of the state’s highest-profile political offices.
Graham, who was seeking a fifth Senate term this November and had been widely expected to win reelection, died Saturday following what his office described as a brief and sudden illness.
Under South Carolina law, Gov. Henry McMaster will appoint an interim senator to serve until voters elect a successor. State election law also establishes a compressed timetable for selecting the Republican nominee who will appear on the November general election ballot.
Republican candidate filing is expected to open July 21, the second Tuesday following Graham’s death, and remain open through July 28.
A special Republican primary is scheduled for Aug. 11. If no candidate receives more than 50% of the vote, the top two finishers will advance to a runoff election on Aug. 25.
Potential candidates emerge
While South Carolina Republicans continue mourning Graham’s death, several prominent GOP figures have already been mentioned as possible contenders.
Among them is Lt. Gov. Pamela Evette, who previously sought the Republican nomination for governor with the backing of Gov. McMaster and President Donald Trump. However, Trump later endorsed South Carolina Attorney General Alan Wilson before the Republican gubernatorial runoff, where Wilson defeated Evette for the nomination.
Rep. Nancy Mace, R-S.C., also acknowledged she is considering entering the Senate race.
“I would be remiss if I didn’t at least consider” a campaign, Mace said during an interview with CBS News on Sunday.
Mace, who was eliminated in the first round of South Carolina’s Republican gubernatorial primary earlier this year, said her immediate focus remains honoring Graham’s legacy.
“Right now, my focus is going to be on South Carolina and mourning the loss of I think one of the greatest senators we’re going to have in our history,” Mace said. “Then I’ll make some considerations to what I do going forward.”
Joe Wilson rules out bid
One Republican who has publicly taken himself out of contention is Rep. Joe Wilson, who said he intends to remain in the House of Representatives.
Wilson said on social media that he spoke with President Trump and reaffirmed his commitment to preserving the GOP’s narrow majority in the House.
“I assured him my goal is to remain in the House to keep his two-vote majority for the American people,” Wilson wrote on X.
Vacancy carries national implications
The race to replace Graham is expected to draw national attention given South Carolina’s importance in Republican politics and the Senate’s closely divided partisan balance.
McMaster has not announced when he intends to appoint an interim senator or whom he is considering for the temporary position.
The winner of the special Republican primary will be heavily favored in the November general election in the reliably Republican state, where Graham had served in the Senate since 2003 after four terms in the U.S. House.
His death creates one of the most closely watched Senate races of the 2026 election cycle as Republicans work to maintain their Senate majority while preserving control of Congress.
