Former Gov. Mark Sanford enters race for Lindsey Graham's Senate seat

Former South Carolina Governor Mark Sanford declared his intention to run for the U.S. Senate seat left vacant after Sen. Lindsey Graham's death, despite President Donald Trump’s endorsement of Graham's sister, Sen. Darline Graham, who was appointed to serve the remainder of the term. Sanford, 66, announced his bid on social media on July 23, saying he is running to "keep the American dream alive for our sons, my grandson, and those you love."

Sen. Darline Graham, who was sworn in on July 14, has said she will seek a full term in the November election. Four other Republicans are also competing for the party’s nomination: U.S. Rep. Russell Fry, attorney Duke Buckner, U.S. Rep. Ralph Norman and businessman Mark Lynch. A recent poll showed Norman ahead of his rivals, while former Rep. Trey Gowdy, who has not formally entered the race, led the poll by a wide margin.

Sanford previously served two non-consecutive periods in the U.S. House of Representatives (1995-2001 and 2013-2019) and two terms as South Carolina governor (2003-2011). His political record includes a 2009 personal scandal and mixed approval ratings during his governorship.

South Carolina voters will hold a special primary runoff on Aug. 11 to determine the Republican nominee for the November Senate election.
