A majority of US voters believe Donald Trump is not fit to be president and only 36 percent approve of the job he is doing in the White House, according to a poll released Wednesday.

Americans were deeply divided by party, gender and race on whether Trump is fit to serve as president, the Quinnipiac University pollsters said.

But most agreed on one thing — Trump should stop tweeting.

Sixty-nine percent of the 1,412 voters surveyed nationwide by Quinnipiac said Trump should step away from Twitter, while just 26 percent said he should continue firing off tweets.

Overall, 56 percent of those polled said Trump is not fit to serve as president while 42 percent said he is fit.

Ninety-four percent of Democrats said Trump, a Republican, was not fit while 5 percent said he is fit.

Eighty-four percent of Republicans said he is fit while 14 percent said he is not.

American men were equally split on the question — 49-49 — while women believed by a 63-35 margin that Trump is not fit to be president.

White voters were divided with 50 percent saying he is fit and 48 percent saying he is not.

Black voters overwhelmingly thought Trump was not fit, by 94 percent to just four percent.

Most Hispanics — by a 60-40 margin — also thought Trump was unfit to be in the Oval Office.

Fifty-seven percent of those surveyed said they disapprove of the job Trump is doing as president with 36 percent saying they approved.

Trump's job approval numbers have hovered between 33 percent and 40 percent in the Quinnipiac polls since March.

Fifty-one percent said they were embarrassed to have Trump in the White House while 27 percent said they were proud.

“There is no upside," said Tim Malloy, assistant director of the Quinnipiac University Poll.

"With an approval rating rating frozen in the mid-thirties, his character and judgement questioned, President Donald Trump must confront the harsh fact that the majority of American voters feel he is simply unfit to serve in the highest office in the land,” Malloy said.

The poll, conducted Sept. 21-26 has a margin of error of plus or minus 3.1 percentage points.
