Rep. Ralph Norman and newly appointed Sen. Darline Graham, sister of the late Sen. Lindsey Graham, have advanced to a runoff in the South Carolina Republican Senate primary, NBC News projects. The runoff election is set for Tuesday, August 25, 2026.

This development comes amid other notable primary results across the United States. Abdul El-Sayed won the Michigan Democratic Senate primary, while Wesley Bell secured a win in a Missouri Democratic primary rematch. In Tennessee, Marsha Blackburn won the GOP primary for governor, and Andy Ogles was defeated in the Tennessee House GOP primary.

These results reflect a dynamic primary season as candidates prepare for the general elections later this year.
