    Scheduled date for the primary runoff election

Sen. Darline Graham (R-S.C.) defended her comments regarding U.S. national security on Wednesday, stating she was being "honest" about her lack of political experience. During a Republican primary runoff debate on Tuesday, Graham told moderators she was "not that informed on national security" when asked about U.S. interests in Taiwan and the South China Sea.

Graham was appointed to the Senate last month to fill the vacancy created by the death of her brother, Sen. Lindsey Graham (R-S.C.). While Lindsey Graham had served in the Air Force for over 30 years and sat on defense-related committees, Darline Graham told Fox News on Wednesday that she does "not speak politician" and is not a career politician.

During the Tuesday debate, Graham’s admission prompted boos from the audience. In response to the question, she stated that she supports the military, and later clarified in her Wednesday interview that she views China as a "military and economic threat" and Taiwan as a "friend." Her primary opponent, Rep. Ralph Norman (R-S.C.), is competing against her for a full term in the seat.

Former South Carolina Governor Nikki Haley criticized Graham's debate performance, stating on social media that national security knowledge is "not something you inherit" and is a critical requirement for a U.S. Senator. Graham countered this by stating that South Carolina voters are more concerned with "making ends meet" and other domestic concerns than with foreign policy in Taiwan.

The roughly 5.4 million residents of South Carolina will see the direct impact of this primary through the representation they receive in the U.S. Senate, an institution with constitutional authority over treaties and military oversight. A senator’s level of expertise can influence federal spending priorities, which in turn affects the $40 trillion national debt mentioned in related economic discussions. Voters will notice this change in how their representative prioritizes domestic versus international policy during legislative sessions and committee hearings.

This contest also serves as a test of political endorsements, as President Trump has recommended and endorsed Graham to replace her brother. The results on Tuesday will indicate the level of influence the former president holds over the state's Republican primary electorate following a high-profile debate stumble. The winner will face the general election cycle to determine who holds the seat for the next six years, shaping South Carolina's role in national security policy for the remainder of the decade.

The runoff election is scheduled to take place on Tuesday. The winner will proceed to represent the Republican ticket in the general election for the full Senate term.
