Former South Carolina Governor Mark Sanford (R) announced Friday that he is endorsing U.S. Rep. Ralph Norman (R-S.C.) in the upcoming Republican primary runoff for the U.S. Senate. The election will determine who serves a full term in the seat previously held by the late Sen. Lindsey Graham (R-S.C.). Sanford, who typically avoids political endorsements, cited the national debt reaching $40 trillion this week as his primary motivation for backing Norman.
The runoff was triggered after neither candidate received a majority of the vote in the Republican primary last week. Current Sen. Darline Graham (R-S.C.), who is Lindsey Graham's sister and was appointed to serve the remainder of his term, is Norman's opponent. Sanford also competed in the initial primary to replace Graham, finishing in fourth place.
In a statement, Sanford described the nation as being at a "financial tipping point" and urged voters to support Norman on Tuesday. Norman responded by stating he was "honored" to receive the endorsement, positioning himself as an experienced candidate ready to take on the role. Meanwhile, Darline Graham maintains support from President Trump, who is scheduled to hold a campaign rally for her in Myrtle Beach on Friday.
The scale of the race involves approximately 5.4 million South Carolinians who will be represented by the winner. For the individual voter, the candidates have presented distinct profiles: Norman emphasizes legislative experience and fiscal concern regarding the $40 trillion national debt, while Graham has faced scrutiny following a recent debate where she stated she was "not that informed on national security" but supported the military. A person living in South Carolina would notice the change in their federal representation immediately following the election results, affecting how their interests are advocated for in Washington regarding taxes, benefits, and foreign policy.
The race also serves as a test of political influence within the South Carolina Republican party. The knock-on effects could influence future policy directions for the state's delegation, particularly as the national debt continues to be a central campaign issue. The primary runoff is scheduled for Tuesday, August 25, 2026, which will serve as the final deadline for Republican voters to select their nominee for the general election.
