South Carolina's entrenched Republican advantage in statewide contests, backed by consistent voter registration edges and past Senate margins exceeding 10 points, underpins the strong trader consensus favoring the GOP nominee at 89%. The death of incumbent Lindsey Graham in July triggered a special primary, with Darline Graham and Ralph Norman advancing to an August 25 runoff after the August 11 vote; whichever candidate emerges faces Democratic nominee Annie Andrews, a pediatrician who secured her party's nod earlier. Limited polling shows Republican leads in head-to-head matchups, while the state's structural factors and absence of major Democratic inroads keep the implied probability of a Democratic win near 11%. The upcoming runoff and November general election timeline remain key variables that could refine positioning.
