Excruciating debate moment as Lindsey Graham’s sister confesses glaring blind spot ahead of runoff campaign: ‘Not that informed’

Darline Graham, the interim South Carolina senator running to permanently succeed her late brother Lindsey Graham, admitted during a Tuesday debate that she was "not that informed" on national security, handing rival Ralph Norman a powerful attack line just days before their runoff. The exchange came after moderator Greta Van Susteren asked whether Taiwan and the South China Sea constituted national security concerns for the US, and Graham's candid but damaging response quickly drew criticism from Republican figures, including Nikki Haley and state senator Matt Leber, who argued the admission undermined her suitability for the Senate seat.

Graham also misstated South Carolina's population, claiming 50 million residents were living paycheck to paycheck when the state's actual population is around 5.5 million, prompting further mockery from figures including former congressman Adam Morgan. Norman, who has built his campaign around experience and foreign policy credentials, seized on both gaffes, while Graham hit back in her closing remarks, attacking his record as "20 years" of limited achievement compared with her "20 days" in office. Graham topped the 11 August primary with 32.7% of the vote to Norman's 24.3%, setting up the 25 August runoff that will determine the Republican nominee for the seat.
