South Carolina

As of Jun 23, 2026

Cook Political Report moved South Carolina's Senate race from Solid R to Lean R, a rating shift that demands explaining in a state where no Democrat has won a U.S. Senate seat since Ernest Hollings in 1998. Sabato's Crystal Ball and Inside Elections hold the seat at Solid R, and the most recent polling, through May 14, shows Republican incumbent Lindsey Graham leading by 6.9 points. The divergence between Cook and the other two raters is itself the story. Graham is seeking a fifth term after a political career that serves as a case study in elite accommodation: McCain-aligned internationalist, then fierce Trump critic, then one of Trump's most reliable Senate defenders, then episodic dissenter again. The whiplash is not ideological incoherence so much as a precise record of which concentrations of power Graham has chosen to serve at each moment. Voters skeptical of donor-class capture (from the libertarian-right or the populist-left) will find Graham's career a useful index of how Washington insiders position themselves relative to shifting factional power rather than durable principle. South Carolina's economy is anchored by Boeing's North Charleston assembly operation, a BMW manufacturing hub in Greer, and a military-installation footprint that gives defense contractors unusual leverage over the state's congressional delegation. Graham's seat on the Senate Foreign Relations and Appropriations committees has made him a central figure in defense-spending debates that directly touch those employers. A fifth term locks in that alignment. Whether the Cook downgrade reflects a real Democratic recruit emerging or a structural readjustment to nationalized polling will determine whether this race gets contested on those terms.
