Overview
- Governor Henry McMaster appointed Darline Graham Nordone to fill the late Sen. Lindsey Graham's seat and President Trump has publicly endorsed her bid for the full term.
- Nordone told a GOP debate Monday that she supports eliminating the filibuster to help pass the Trump-backed SAVE America Act, a position she said differs from her brother's record.
- Polls and prediction markets show mixed signals and a high share of undecided voters, indicating Trump's endorsement has not fully consolidated Republican support in the compressed race.
- The special Republican primary is scheduled for Aug. 11 and party rules would trigger an Aug. 25 runoff if no candidate wins a majority, a result many GOP operatives now expect.
- Control stakes are national: the winner will influence whether Republicans can change Senate rules and advance high-priority measures on voting and other Trump-backed policies.
