South Carolina's U.S. Senate contest remains heavily tilted toward the Republican nominee due to the state's consistent partisan alignment and historical voting patterns. Lindsey Graham's July 2026 death triggered a compressed special primary process, with his sister Darline Graham appointed to the seat and advancing to an August 25 runoff against Representative Ralph Norman following the August 11 primary. Democratic nominee Annie Andrews secured her party's nod but faces structural barriers in a state where Republicans have held both Senate seats for decades and no Democrat has won a Senate election since 1998. Trader consensus reflected in current pricing incorporates the limited impact of the primary disruption, ongoing Republican primary consolidation, and the absence of competitive general-election polling shifts capable of altering the outcome by November.
