Darline Graham, appointed in July 2026 to temporarily fill the late Senator Lindsey Graham’s seat, is seeking a full six-year term as U.S. Senator from South Carolina [1, 2]. During the Republican primary debate on August 18, she was asked whether Taiwan and the South China Sea are U.S. national security issues [1, 3]. Graham replied, “National security is not my expertise,” admitting she did not understand those issues well [1, 4]. She emphasized her support for the military but said her focus is mostly on domestic matters like food prices, gasoline, and healthcare costs [1, 5].
Graham’s admission drew criticism from some Republicans, including her runoff opponent Ralph Norman and former South Carolina governor Nikki Haley [1, 6]. Norman confidently stated, “Taiwan is absolutely an ally,” and praised former President Trump for helping Taiwan defend itself against China [1]. Haley said Lindsey Graham was deeply knowledgeable on national security, whereas Darline Graham admitted she was not, adding, “This kind of thing cannot be inherited and is crucial in the U.S. Senate” [6].
Darline Graham has never held elected office before and was appointed following Lindsey Graham’s sudden death in July 2026, a senator well-known for his foreign policy expertise and multiple visits to Taiwan [1, 2, 5]. The discussion and debate have sparked analysis noting many American politicians lack deep knowledge of Taiwan or foreign affairs, focusing more on domestic issues instead [7]. A political scientist commented, "It is not unusual that U.S. politicians, including Graham, are not well versed on Taiwan" [7].
After the debate, Graham told Fox News that her answer was a mistake and reiterated she is not a seasoned politician or national security expert [3, 4]. President Donald Trump publicly defended her, calling her “very smart and very honest” and praising her openness about not knowing national security details as “a very honest answer” [3, 8].
The South Carolina Republican special primary runoff between Darline Graham and Ralph Norman is set for August 25, 2026 [1, 2]. The winner will compete in the general election for the full six-year Senate term left vacant by Lindsey Graham.
