South Carolina's 4th Congressional District, with a Cook Partisan Voter Index of R+11, has delivered consistent Republican victories, including incumbent William Timmons' 59.7% win in 2024, fueling trader consensus at 88.5% for the Republican Party in the November 3 general election. Timmons, who recently filed for re-election with a fundraising edge ($125,000 cash on hand), faces primary challengers David Atchley and Robert Lee in the June 9 GOP primary, where he remains favored despite the field's emergence by the March 30 filing deadline. Democrat Courtney McClain advances unopposed, but historical general election margins exceeding 20 points underscore formidable barriers absent a primary upset or national Democratic midterm surge.
