The essentials
South Carolina holds special primary August 11 for Graham's Senate seat with Trump-backed appointee and Democratic nominee competing.
South Carolina is holding a special primary election on August 11 to select Republican and Democratic candidates for the Senate seat vacated by Senator Lindsey Graham's death. President Trump has endorsed Darline Graham Nordone, Graham's sister who was appointed to fill the seat temporarily by Governor McMaster.
Democrat Annie Andrews won the Democratic Senate nomination, positioning herself as the Democratic challenger. The special primary process faces a conflict with federal military ballot requirements, complicating the election timeline.
Darline Graham was sworn in as interim senator and brings a background in disability services and state government to the role. She will serve until early January 2027, when an elected successor takes office. The succession combines the interim appointment mechanism with primary and general election processes, establishing the pathway for filling Graham's vacant seat.
