Overview
- Gov. Henry McMaster appointed Darline Graham Nordone to the Senate after her brother’s sudden death, and she was sworn in this week to serve the remainder of his term.
- Darline Graham privately told the White House she may run for a full six-year term and has already engaged in Senate work by joining a Russia sanctions bill.
- President Trump publicly urged her to run and posted a “complete and total endorsement” on July 17, shifting the balance among likely Republican contenders.
- The Republican filing window runs July 21–28 and a special primary is set for Aug. 11 with a possible Aug. 25 runoff, creating a compressed race that favors quick organization.
- Early polls show no clear GOP favorite and many voters undecided, and campaign rules limit direct transfers from Lindsey Graham’s campaign though party groups can provide outside support.
