Darline Graham's debate remark sparks debate over campaign strategy in South Carolina Senate runoff

Sen. Darline Graham, who was appointed to the U.S. Senate seat vacated by her brother Lindsey Graham, faced criticism after saying during a debate that "national security is not my thing." The remark, made while answering a question on Taiwan and the South China Sea, has been interpreted by some political observers as an intentional effort to differentiate herself from Rep. Ralph Norman, her opponent in the Republican runoff scheduled for Tuesday.

One state GOP operative suggested the comment might have been a strategic choice aimed at generating sympathy, while a separate GOP source described the remark as a significant misstep that could alienate older voters. Graham has continued to reference the statement in campaign messaging, positioning herself as relatable and portraying Norman as a career politician.

The race is drawing substantial outside spending. The Invest in Tomorrow Coalition has contributed more than $1 million to ads attacking Norman for his past support of a pro-solar coalition and opposition to certain federal subsidies. The Security is Strength PAC, linked to Lindsey Graham, has spent about $1.5 million, including mailers that label Norman a "MAGA traitor."

President Donald Trump visited Myrtle Beach on Friday and met with Graham, urging voters to support her. He said, "She said that she’s totally for the military. She’s going to do what the military wants, and really what the president wants."

Norman, who previously endorsed former Gov. Nikki Haley before withdrawing his endorsement, received support from former Gov. Mark Sanford, who posted on X about concerns over the nation’s fiscal situation. Sanford has longstanding personal ties to the Graham family.

The runoff will determine who completes the term left vacant by Lindsey Graham’s death last month.
