Darline Graham Wins Republican Runoff for South Carolina Senate Seat
Darline Graham won the Republican primary runoff for South Carolina's U.S. Senate seat on August 25, 2026. She defeated U.S. Representative Ralph Norman and moved closer to keeping the office previously held by her late brother, Senator Lindsey Graham. The Associated Press projected Graham as the winner. The runoff was held across all 46 counties in the state, according to the South Carolina State Election Commission.
The runoff was part of a special election — an election held outside the normal schedule — triggered by the vacancy created when Lindsey Graham died. Darline Graham, who had no prior political experience, was appointed to fill the seat before facing voters. She defeated Norman in the second round of voting after no candidate got a majority in the first round. NBC News and The New York Times both reported the outcome on August 26.
Early voting opened Wednesday, August 19, 2026, giving voters a three-day window before Election Day on Tuesday, August 25. The South Carolina State Election Commission also conducted hand-count audits, meaning officials manually recounted ballots to double-check the results.
President Trump publicly praised the power of his endorsement after Graham's victory, as NPR reported on August 26. Trump had backed Graham in the race and said the result showed his endorsement still carries weight in Republican primaries.
The contest drew national attention for several reasons. It tested the influence of a presidential endorsement in a state that reliably votes Republican. It tested whether a political newcomer appointed to the seat could beat an experienced member of Congress. And it involved the unusual situation of a sibling trying to succeed a late senator from the same family. Norman currently represents South Carolina's 5th Congressional District and brought a voting record to the race. Graham's campaign relied on her appointment to the seat and the backing of the White House.
The result keeps the seat in the Republican column heading into the general election. South Carolina has not elected a Democrat to the Senate since 1998. Graham's victory settles which Republican will appear on the November ballot, unless a serious third-party or write-in candidate emerges. ABC News also projected Graham as the winner.
The broader context here is how the appointment process worked in a race where the appointee had never run for office before. When a Senate seat becomes open, the state's governor appoints someone to fill it. That person then decides whether to run to keep the seat or step aside. Graham chose to run, and voters made their decision in the runoff. The hand-count audit by the South Carolina State Election Commission is a standard step the state uses to verify election results in high-profile contests.
Looking at what this means for Republicans, Graham's win locks in an advantage in a state the party has held for decades. The result also adds to the debate over how much Trump's endorsement matters in primaries for offices below the presidential level, especially when the endorsed candidate has a family connection to a well-known former officeholder.
The general election in November will determine whether Graham wins a full term. The state's partisan lean makes her the favorite. The runoff result settles the Republican side of a race that began with a vacancy and now has a nominee.
