South Carolina Senate

There's no live forecast for the 2026 South Carolina Senate race: every poll on file asks about Lindsey Graham, who lost the Republican primary to Darline Graham, and nobody has polled the new matchup yet.

Nominee changed — Graham nominated in the runoff

Lindsey Graham, who had won the June 9 Republican primary, died on July 11, 2026. Gov. Henry McMaster appointed his sister Darline Graham to serve the remainder of the term, and she was nominated in the August 11 special primary runoff to face Democrat Annie Andrews in November. The nominee is known; every poll on file asks about Lindsey Graham, so the forecast returns once a pollster asks about the new matchup.

No forecast is published for this race. Darline Graham is the Republican nominee; the forecast returns once a pollster asks about the new matchup.

Lindsey Graham lost the primary on July 11, 2026. Because this seat has no forecast, it is held out of the Senate-control simulation rather than counted for either party. source
