South Carolina’s 4th Congressional District maintains a strong Republican lean with an R+11 Partisan Voter Index, where incumbent William Timmons secured renomination in the June primary by a wide margin and enters the November general election with endorsements and fundraising advantages. Nonpartisan forecasters rate the race Solid or Safe Republican, consistent with Timmons’s 22-point victory in 2024 and the district’s support for Republican presidential candidates. Democratic nominee Courtney McClain, a first-time candidate, faces structural barriers in a district that has elected Republicans continuously since 1993. Trader consensus reflected in the current pricing assigns overwhelming probability to Timmons absent late developments such as a major scandal, health event, or sharp national swing that alters turnout patterns before Election Day.
