Embarrassing: Darline Graham Flubs Simple Debate Question

Interim U.S. Sen. Darline Graham delivered a widely circulated gaffe during a Republican primary runoff debate Tuesday when asked about Taiwan and the South China Sea. Facing U.S. Rep. Ralph Norman, Graham responded candidly that national security was not her area of expertise.

Moderator Greta Van Susteren asked: “Are Taiwan and the South China Sea national security issues for the United States? If so, why?” Graham replied: “I’m just going to be honest here. I’m not… that informed on national security, so… but I do support the military.” She continued: “I’m not a polished politician up here. National security is not my thing, not my area of expertise, but I do support the military,” noting that her late brother had served in the Air Force.

The exchange quickly went viral. Critics highlighted it as evidence of qualification concerns for a full six-year Senate term. Graham was appointed by Gov. Henry McMaster after the death of her brother, the late Sen. Lindsey Graham, and is seeking the remainder of that term in the Aug. 25 runoff.

She finished first in the Aug. 11 special primary with just over 30 percent of the vote, advancing against Norman. Other candidates included U.S. Rep. Russell Fry, former Gov. Mark Sanford, and businessman Mark Lynch. Graham has received endorsements from President Donald Trump and Fry.

Before her appointment she worked in vocational rehabilitation and led the South Carolina Commission for the Blind. The debate occurred one day before early voting began. The viral moment has intensified scrutiny of her readiness for the national security responsibilities of a U.S. senator.

“I’m just gonna be honest—I’m not that informed on national security.”

The main criticism is that she’s not qualified for this 6-year position.
