South Carolina's U.S. Senate race favors the Republican nominee due to the state's consistent partisan lean, where no Democrat has won a Senate seat since 1998. The death of four-term incumbent Lindsey Graham in July 2026 triggered a special Republican primary, with his sister Darline Graham appointed interim senator and advancing to an August 25 runoff against Rep. Ralph Norman. Pediatrician Annie Andrews secured the Democratic nomination. Race ratings from Cook, Sabato, and others classify the contest as solid or safe Republican. Trader consensus reflects these structural advantages and limited recent Democratic competitiveness in the state, though the imminent runoff and November general election leave room for shifts based on primary turnout or campaign developments.
