The Race to Replace Sen. Lindsey Graham: A South Carolina Senate Showdown
7/20/2026, 12:19:52 AM
Core Event
Sen. Lindsey Graham (R-SC), who had served in the U.S. Senate since 2003, died on July 11, 2024 from an aortic dissection. His death created an open seat in a state that has voted Republican in every presidential election since 1980 and last elected a Democratic senator in 1998. The vacancy triggers a special primary on August 11, 2026, with a possible runoff on August 25, and a general election in November.
Background & Context
Graham was the Republican front-runner for the 2026 Senate race, having won the June 9 primary with 57 % of the vote. South Carolina’s political landscape is heavily Republican: President Donald Trump carried the state by 18 points in 2024, and the GOP has held every Senate seat since 1998. The sudden loss forces the party to select a new nominee while Democrats see a rare opening.
Key Figures & Groups
- Dr. Annie Andrews – Democratic nominee, pediatrician, former 2022 congressional candidate.
- Rep. Ralph Norman (R-SC-5) – First Republican to announce a Senate bid; former House member.
- Mark Lynch – Greenville businessman, confirmed candidate, pledged an additional $5 million.
- Rep. Nancy Mace (R-SC-1) – Potential candidate, former House member.
- Rep. Russell Fry (R-SC-7) – Potential candidate, close to President Trump.
- Lt. Gov. Pamela Evette – Potential candidate, noted the “disheartening” timing.

Data & Statistics

- Impact Research poll (June 17-22, 700 voters): Republican candidate (still listed as Graham) 48 % vs. Andrews 45 %.

- Measles outbreak in South Carolina: nearly 1,000 documented cases, cited by Andrews as a consequence of vaccine refusal.
Why It Matters
The seat has been a “senate whisperer” for Republican leadership on foreign policy. Its loss could weaken GOP coordination with the Trump administration and shift the Senate balance if Andrews wins. Democrats view 2026 as a potential turning point, citing President Trump’s declining national approval and economic concerns.
Official Statements & Responses
- Andrews emphasized that the “problems that South Carolinians face didn’t change over the weekend” and reiterated her focus on health-care, impeachment of RFK Jr., and Medicaid funding.
- Norman pledged to “carry on the late Sen. Lindsey Graham’s legacy” and highlighted the “SAVE America Act.”
- Governor Henry McMaster appointed Darline Graham to serve until January 3, 2027, noting the appointment is temporary.
- Trump posted on Truth Social urging Darline Graham to run, calling her “the best” to honor her brother’s legacy.
Criticism & Opposition
Andrews reported that many Republicans now say the party has become “too extreme” and needs to return to a “center-right” identity reminiscent of John McCain. She argues that a competitive Senate race could force the GOP to “self-correct.” Some Republican figures, including former Governor Nikki Haley and Treasury Secretary Scott Bessent, have publicly declined to run, limiting the field.
Conflicting Reports & Gaps
Polls differ on the leading Republican contender; Norman leads in the Emerson poll, while the Impact Research poll still lists Graham as the hypothetical nominee. Darline Graham has not confirmed whether she will seek a full term, leaving a key potential candidacy uncertain.
