A majority of registered voters say that President Trump Donald John TrumpBiden says voters should choose who nominates Supreme Court justice Trump, Biden will not shake hands at first debate due to COVID-19 Pelosi: Trump Supreme Court pick 'threatens' Affordable Care Act MORE's endorsement makes them less likely to vote for a candidate, according to a new American Barometer survey.

The poll, conducted by Hill.TV and the HarrisX polling company found that 57 percent of respondents said Trump's backing of a candidate would make them less likely to vote for that candidate.

Forty-three percent said they were more likely to vote for a candidate that had been endorsed by the president.

The poll found a heavy partisan divide on the question with 81 percent of Republicans saying Trump's endorsement would make them more likely to vote for the candidate, and 85 percent of Democrats saying it would make them less likely vote for the candidate.

"It's a mirror image of the approval ratings, and it just shows how divided the country is," conservative political analyst Henry Olsen told Hill.TV's Joe Concha on "What America's Thinking."

"Of course as it plays out in the Senate races, a lot of the Senate seats that Democrats are defending probably have approval at or above 50 percent, which means that going in this last week into these places that is trying to bring these voters home, and say 'don't split your ticket. If you like me, vote against the guy who doesn't like me."

Trump is actively campaigning for Republican candidates across the country ahead of the election, which is expected to be a referendum on his first two years as president.

The president enjoys a high approval rating among his own party, with 89 percent of Republicans saying they approve of his job in office, according to a recent Gallup poll.

Thirty-seven percent of independents say they approve of Trump's job as president, and only 6 percent of Democrats said they approved.

The American Barometer was conducted on October 27-28 among 1,200 registered voters. The sampling margin of error is plus or minus 2.83 percentage points.
