Ten percent of Americans said President Trump Donald John TrumpBiden on Trump's refusal to commit to peaceful transfer of power: 'What country are we in?'

The American Barometer survey, conducted by Hill.TV and the HarrisX polling company, found that 10 percent of respondents specified Trump was the biggest threat to America, with 26 percent picking an attack by terrorists.

“Overall, it’s a relatively small number," former Obama campaign strategist Joel Benenson told Hill.TV's Joe Concha on "What America's Thinking," referring to the 10 percent.

"At the same time, what you’ve had is a vibrant debate going on about his attacks on the rule of law, on the First Amendment, the freedom of the press,” Benenson added. “I think what you have here is some people who are interpreting that question in terms of the attack on the rule of law -- both the FBI, our intelligence agencies ignoring Russia’s interference in our election -- and then attacking our democratic institutions."

The American Barometer was conducted Sept. 8-9 among 1,000 registered voters. The sampling margin of error is plus or minus 3.1 percentage points.

Other polling has shown that many Americans say Trump's policies pose a major threat to the U.S.

A Public Religion Research Institute (PRRI) survey conducted last year found that 46 percent of Americans polled agreed that "Trump’s policies are so misguided they constitute a serious threat to the country."

Americans polled by PRRI appeared more likely to view Trump as dangerous to the nation compared with policies put forth by the two major political parties. Twenty-seven percent of respondents said that Democrats' policies were a serious threat, while 30 percent said the same about Republican policies.
