Honesty is generally a good quality in a politician. But when someone is already serving in the United States Senate and asking voters to keep her there, admitting that she is not well informed about a major national security issue is going to get attention.
Sen. Darline Graham found that out Tuesday night during a Republican primary debate in South Carolina.
Newsmax anchor Greta Van Susteren asked Graham a fairly straightforward question: “Are Taiwan and the South China Sea national security issues for the United States?”
What followed was an uncomfortable moment for Graham.
She first asked Van Susteren to repeat the question. After a pause, she acknowledged that foreign policy was not an area where she felt particularly knowledgeable.
“I’m gonna be honest here,” Graham said. “I’m not a national security that … I’m not that informed on national security so … But I do support the military.”
She then talked about her family’s military background, mentioning her late brother, Sen. Lindsey Graham, and his service in the Air Force, along with their father’s service in the Army.
“I’m not a polished politician up here,” she added.
That much was obvious. But the larger problem was not a lack of polish. It was the subject she had been asked about.
Taiwan and the South China Sea have been central to American foreign policy discussions for years. China has become increasingly aggressive in the region, while Taiwan remains economically and strategically important to the United States. Taiwan is also a major producer of advanced semiconductors that are essential to American technology and industry.

A candidate for Senate does not need to be a foreign policy scholar, but voters can reasonably expect a senator to understand why China, Taiwan and the South China Sea matter.
Graham’s circumstances make the exchange even more striking because she is not simply campaigning for an office she has never held. She is already a senator.
South Carolina Gov. Henry McMaster appointed Graham to fill the seat after her brother’s death in July. She later finished first in the Republican primary on Aug. 11 but failed to receive enough support to avoid a runoff. She now faces Rep. Ralph Norman in the Aug. 25 runoff election.
Norman gave a much more conventional answer to the same foreign policy question, arguing that the United States should approach China with a “peace through strength” strategy.
The contrast was hard to miss.
It was also notable given Lindsey Graham’s long record of interest in foreign affairs. After his death, Taiwan’s government publicly praised him for his support of Taiwan-U.S. relations and for his role in promoting stability across the Taiwan Strait.
Darline Graham clearly has a different set of priorities.
After the debate, reporters gave her another opportunity to explain her answer. Rather than walking it back, she essentially doubled down.
“They’re worried about their pocketbooks more than they’re worried about the South China Sea, quite honestly,” Graham said, according to The Associated Press. “So that’s going to be my biggest focus.”
There is some political logic behind that argument. Most voters probably do spend more time thinking about grocery prices, jobs, taxes and household expenses than naval tensions thousands of miles away.
But senators are elected to deal with both.
Foreign policy becomes especially important when the issues involve China, international trade, military alliances and the possibility of armed conflict. A voter does not have to follow every development in the Taiwan Strait. A United States senator has considerably less room to tune it out.
The episode brought back memories of other memorable debate failures.
During a 2011 Republican presidential debate, then-Texas Gov. Rick Perry famously struggled to remember the third federal department he wanted to eliminate. After naming Commerce and Education, he could not recall the Department of Energy and eventually ended the exchange with, “Oops.”
That mistake followed Perry for years, although it was clearly a temporary mental blank. In a strange twist, Perry later became secretary of energy under President Donald Trump.

Graham’s answer was different because she was not struggling to remember a fact she already knew. She openly acknowledged that she was not well informed about the issue.
There is something refreshing about a politician admitting what she does not know instead of filling the air with rehearsed talking points. Still, honesty does not erase the underlying problem.
Graham entered the race with advantages few candidates could hope to have. She carries one of the best-known political names in South Carolina, inherited the Senate seat her brother held for years and has received President Trump’s endorsement.
Tuesday’s debate, however, put the focus on something that family connections and endorsements cannot answer for her: whether she is prepared for the full responsibilities of the job.
Economic concerns may be her preferred focus, and they may be the top concern for many South Carolina voters. But the Senate does not allow its members to choose between domestic issues and national security. They are expected to deal with both.
That is why a single debate answer has become such a significant moment in Graham’s campaign. The issue was not that she stumbled over a complicated policy proposal. It was that she admitted she did not know much about one of the most consequential national security questions facing the United States.
