Sen. Darline Graham (R-SC) and Rep. Ralph Norman (R-SC) sparred during a GOP Senate debate on Tuesday over national security and domestic policy.

The outcome of this contest determines which Republican will succeed the late Sen. Lindsey Graham in the U.S. Senate. With early voting beginning tomorrow, the debate served as the final major confrontation before voters head to the polls.

The candidates disagreed on a wide range of issues, including Medicare, immigration, and the role of artificial intelligence in government. Much of the discussion centered on the current war in Iran and the broader implications for U.S. national security.

During the exchange, Sen. Graham addressed her own level of expertise on foreign policy. "I'm not that informed on national security," Graham said [3].

The event took place just before the Aug. 25 runoff election [1]. While the candidates sought to define their platforms for the remaining undecided voters, news outlets differed on the primary outcomes of the evening. The Hill reported three key takeaways from the event [2], while The State identified five [4].

Rep. Norman focused his arguments on policy differences and the need for a specific approach to the Senate seat. The candidates continued to clash on how to handle the vacancy left by the death of Sen. Lindsey Graham, emphasizing their differing visions for the state's representation in Washington.

"I'm not that informed on national security."

The runoff election represents a critical pivot point for the South Carolina GOP, as the party decides between the established legislative approach of Sen. Graham and the challenge posed by Rep. Norman. The admission regarding national security expertise may become a central point of contention in the final hours of the campaign, particularly given the volatility of the conflict in Iran.
