U.S. Sen. Darline Graham stumbled during a Tuesday night debate in Newberry, South Carolina, when moderators asked whether Taiwan and the South China Sea represent national security issues for the United States, according to Apnews reports. The debate at the historic Newberry Opera House took place exactly one week before South Carolina Republican primary voters head to the polls for a runoff election on August 25, 2026, as detailed by NBC News.
National Security Misstep Trips Up Interim Senator in Debate
Faced with the elementary foreign policy question—a signature issue historically championed by her late brother—Graham hesitated before offering a blunt assessment to the audience, according to The Guardian. I’m just going to be honest here,
Graham said during the August 18, 2026 encounter. I’m not that informed on national security, so—but I do support the military.
She added, I’m not a polished politician up here; national security is not my thing, not my area of expertise, but I do support the military.
Gasps and boos reportedly rolled through the venue in response, and she frequently read notes from a legal pad draped over her lectern during the proceedings.

High Stakes in South Carolina GOP Runoff
The Senate seat was previously held by Lindsey Graham, one of the Senate’s most prominent foreign policy hawks, who passed away suddenly on July 11, 2026. Following his death, Darline Graham—a political newcomer who had never run for public office or been active in state or local politics—was appointed as interim senator by state officials last month. She is now running in a special election to secure a full six-year term.
In last week’s primary election on August 11, 2026, Graham and her runoff opponent, U.S. Rep. Ralph Norman, finished first and second among a 10-candidate field. Because no candidate secured the majority needed to win outright, the race moved to the upcoming August 25 runoff. Early voting in the state begins on Wednesday.
Opponent Criticizes Qualifications and Washington Backing
Norman seized on the foreign policy stumble during the debate, arguing that the exchange demonstrated Graham is unqualified for the position. By her choice, she’s running for the United States Senate. It’s a six-year term,
Norman stated during the debate. You need to get fully versed in what issues you’re going to be dealing with.

Norman also criticized his opponent’s ties to the political establishment, telling voters that Washington supports Graham while painting himself as an outsider. Graham countered by questioning Norman’s political consistency, referencing his unsuccessful campaign in the state’s June gubernatorial primary. President Donald Trump has endorsed Graham in the race, and a presidential visit to South Carolina is scheduled for Friday to campaign on her behalf ahead of the primary runoff. The winner of the Republican nomination will face Democratic candidate Annie Andrews in the November general election.
Focusing on Everyday Voter Concerns
When speaking with reporters after the debate, Graham defended her focus and declined to take another crack at answering the moderators’ foreign policy question. Instead, she emphasized that everyday economic issues remain the top priority for her constituents. They’re worried about their pocketbooks more than they’re worried about the South China Sea, quite honestly,
Graham told reporters. So that’s going to be my biggest focus.
Despite her admission regarding foreign policy expertise, Graham noted during post-debate remarks that she had addressed the broader national security threat posed by China multiple times throughout the evening. She also highlighted her family’s military background, noting that her late brother served 33 years in the Air Force and her father served in the Army.
