The unexpected death of U.S. Sen. Lindsey Graham, who was campaigning for a fifth term, has initiated a significant political transition in South Carolina. Gov. Henry McMaster is tasked with appointing an interim senator to serve until January, while the state simultaneously gears up for special elections to determine Graham's permanent successor.
The open Senate seat has prompted intense competition among prominent South Carolina Republicans. The state's GOP recently concluded a strenuous nomination contest for governor, with Attorney General Alan Wilson securing the Republican nomination. Several figures who vied for the gubernatorial nomination, including Lt. Gov. Pamela Evette, U.S. Rep. Nancy Mace, and Rep. Ralph Norman, are now considered potential contenders for Graham's Senate seat.
According to state law, a one-week filing period for the special primary election will commence on July 21, two weeks after Graham's death. The special primary is scheduled for August 11, with a potential runoff on August 25. The newly chosen Republican nominee will then have slightly over two months to campaign for the general election on November 3.
This compressed timeline presents logistical challenges, particularly concerning federal regulations requiring military and overseas ballots to be distributed 45 days before a federal election. For the general election primary, this deadline would have been June 27. Federal Election Commission officials have not yet provided clarification on how these requirements will be met.
Graham died over the weekend, with a preliminary medical examiner's report indicating an aortic dissection as the cause. In the immediate aftermath of his death, speculation began circulating within South Carolina's Republican party about potential appointees. Given the proximity to the November election, any interim appointee by Governor McMaster could be a strong candidate in the special primary, though they might also serve solely as a caretaker.
Lt. Gov. Pamela Evette, who has served nearly eight years and received Governor McMaster's endorsement in her recent gubernatorial bid, is seen as a possible appointee. She recently lost her bid for the Republican gubernatorial nomination in a runoff. Sources close to Evette suggest she is receiving encouragement statewide and believes she has a strong chance in a special primary.
It is considered unlikely that a current House member would be appointed to complete Graham's current term, due to the Republican party's narrow majority in the chamber. U.S. Rep. Joe Wilson stated he assured President Trump his priority is to remain in the House to maintain the Republican majority. However, House members may still pursue the nomination for the full term, with Rep. Nancy Mace reportedly considering a run. She is not seeking reelection to the House. Rep. Russell Fry, a two-term lawmaker and an ally of President Trump, is also considered a potential candidate.
Businessman Mark Lynch, whom Graham defeated in the primary, did not immediately respond to inquiries. Treasury Secretary Scott Bessent, who previously resided in South Carolina, has reportedly fielded calls about the position but has expressed no interest, preferring to continue his work with the Trump administration.
Historically, Democrats have not secured a Senate seat in South Carolina for decades, with Republican statewide victories typically occurring by significant margins. In his 2020 reelection, Graham defeated his Democratic opponent, Jaime Harrison, by 10 percentage points.
Charleston pediatrician Annie Andrews secured the Democratic nomination and has shown strong fundraising capabilities. In a statement, Andrews encouraged South Carolinians to unite in gratitude for Graham's service. Jaime Harrison, reflecting on his past political contests with Graham, noted a mutual respect for South Carolina and its institutions.
Graham's death creates a significant vacancy in the Senate, where seniority plays a crucial role in influence and committee leadership. He had served more than two decades in the chamber. South Carolina's junior senator, Tim Scott, has served since 2012. Scott, who co-chaired Graham's reelection campaign, described his colleague as "irreplaceable" and a "statesman."
