South Carolina Sen. Darline Graham has given opponents fresh ammunition to attack her on her biggest vulnerability: her inexperience.
She revealed a major blindspot in her understanding of a critical foreign policy issue, U.S.-Taiwan relations, during Tuesday's debate for the Aug. 25 snap Senate primary runoff to replace her late brother Lindsey Graham. Her response spread like wildfire on social media, with critics saying it proves she is “unprepared” to take office.
Asked whether Taiwan and the South China Sea are relevant national security priorities, Graham responded: “I'm just going to be honest here … I'm not that informed on national security, so.” She added that “national security is not my thing, not my area of expertise, but I do support the military.”
It was a notable acknowledgement from a sitting senator, as tensions rise between China and Taiwan — and as the U.S. preoccupation with the Iran war calls into question how reliable a supporter it might be amid fears of a possible future invasion of Taiwan.
The gaffe exposed the exact weakness that her runoff opponent, GOP Rep. Ralph Norman, has been eager to highlight: the senator’s lack of tenure.
His allies immediately piled on.
Norman supporter and former U.N. Ambassador Nikki Haley wrote in a post on X that foreign policy experience is “not something you inherit” — a swipe at Graham’s appointment to fulfill her brother’s current term. Ken Cuccinelli, a former Trump administration official, expressed support for Norman, writing that Graham has “worked hard to hide any firm positions, and here she is at least being honest.”
“It very much confirmed many of our suspicions that while she might be a very nice lady, she is woefully underprepared or unprepared to be one of the 100 U.S. Senators in the Senate,” state Rep. Jordan Pace, who is supporting Norman in the runoff, said in an interview.
Norman said in a statement that South Carolinians deserve a senator with “know-how” on foreign policy: “Whether it’s spy balloons flying overhead or buying up land near South Carolina military bases, China continues to prove that it is a threat to the United States.”
Graham’s campaign, asked to clarify her response on U.S.-Taiwanese relations and her critics’ attacks over her misstep, pointed toward comments she made in the spin room after the debate: “What's important are the people of South Carolina. They're worried about their pocketbooks more than they're worried about the South China Sea, quite honestly.”
Graham’s answer is also raising eyebrows among some of her own allies, with less than a week before next Tuesday’s election. And it increases the pressure on President Donald Trump, who had championed Graham’s appointment in July, encouraged her to run for a full term and is even planning to rally with her on Friday to boost her election chances.
"[Darline] just doesn’t have the experience of executing, you have to be able to deliver a story about herself and right now her story is that she’s Lindsey Graham’s sister,” said a former Trump administration official, granted anonymity to speak openly about private conversations.
The White House is still backing Graham, this person said, because the president had a close relationship with the late senator but also sees her as a better alternative to Norman, who endorsed Haley over Trump in the 2024 Republican presidential primary.
A second person familiar with the White House’s thinking, granted anonymity to speak candidly, said, “POTUS is still all in on the endorsement.”
The White House declined to comment on Trump’s support for Graham.
Still, the flub highlighted the danger for Trump, as he seeks to propel a political novice into a six-year term in the Senate and avoid yet another stain on his endorsement record. His high-profile rally for Graham in Myrtle Beach later this week is a particularly notable step in a year otherwise marked by a decrease in his explicit campaign travel.
Norman, for his part, said during the debate that Taiwan is a “definite ally” and that Trump is right to enable them to “defend themselves against China.” He declined to take a swipe at Graham over her comment in real time, but that hasn’t stopped his supporters from hammering the newcomer for the embarrassing misstep.
Graham’s stumble was a far cry from her late brother’s hawkish defenses of Taiwan, in which Lindsey Graham had openly criticized the expansionist aims of Chinese President Xi Jinping, called allies of China “dirtbags” and stressed the need to maintain the status quo between Beijing and Taipei to protect U.S. national security interests.
“Anyone running for a seat in Congress should be able to explain to the American people why Taiwan is important to American interests. Taiwan is a vibrant democracy of 23 million people and the source of over 90 percent of the world's advanced semiconductors,” said Bonnie Glaser, managing director of the German Marshall Fund’s Indo-Pacific program. “A Chinese takeover by force would shatter U.S. credibility with its allies across the Indo-Pacific.”
American intelligence has long suggested that China’s People’s Liberation Army will be sufficiently capable of seizing the island starting in 2027.
Trump in June said he was open to speaking with Taiwan’s President Lai Ching-te, despite China’s warnings against doing so, in what would be the first direct dialogue between American and Taiwanese leaders in decades.
But the U.S.’ war with Iran is casting doubt on how effective an ally the Trump administration will be if China does invade Taiwan. Extended naval deployments to support airstrikes against Iran and a corresponding blockade of its ports have left the U.S. without a deployed aircraft carrier in the Indo-Pacific, as the USS George Washington steams toward the Middle East to relieve the extended Abraham Lincoln carrier, for instance.
The heightened risks and the rapid race to replace Lindsey Graham have left some in South Carolina’s GOP circles feeling less than optimistic about the choice they have to make to select a key proxy in Washington.
“It was shocking how we're gonna give someone who was on stage last night six years in the U.S. Senate, and I think that’s the overall impression people are having today” said one South Carolina-based Republican operative who has stayed neutral in the Senate race and was granted anonymity to speak candidly. “One of these two is gonna get six years in the Senate? Like, big hanging question mark.”
