Core Event
Senator Lindsey Graham (R-SC) died on July 11, 2026 after a “brief and sudden illness,” prompting Governor Henry McMaster to appoint Graham’s sister, Darline Graham, as interim senator.

Early voting is set for August 5-7, the primary for August 11, and a runoff, if needed, for August 25.
