President Donald Trump should stop tweeting, the vast majority of voters said in a Quinnipiac poll released Wednesday.

A whopping 70% of voters think the president should stop tweeting from his personal account, @realdonaldtrump, a number that has continued to grow over time.

Trump in recent weeks has used Twitter to castigate professional athletes including NFL players and NBA star Steph Curry, criticize members of his own party, such as Sens. Bob Corker and John McCain, and tease threats of a nuclear conflict with North Korea.

Overall, 56% of voters disapprove of Trump's job performance as president, compared to 57% in the September poll, and 55% said he isn't fit to serve in office. However, 81% of Republicans approve of Trump, while only 12% disapprove.

"After a turbulent stretch of heartbreaking tragedies, President Donald Trump is still deep in negative territory," Tim Malloy, assistant director of the Quinnipiac University Poll, said in the press release.

Voters are more evenly split on Trump's handling of the economy: 48% of voters approve, while 46% of voters disapprove. A total of 61% of voters — close to an all-time high, notes Quinnipiac — said the country's economy is "excellent," or "good," while 37% said it is "not so good" or "poor."

However, 72% of voters are either "somewhat dissatisfied" or "very dissatisfied," with the country's direction overall.

"Trump may not be fit, but the economy is, voters said," Malloy continued. "They remain troubled by the president's competence, but see the economy booming along under his stewardship."

Responding to Trump's comments on the NFL protests, 58% of voters said they weren't appropriate, while 67% of voters said they agree with the president's comments. Just over half of voters disapprove of NFL players taking a knee during the national anthem, though 66% of millennial voters between the ages of 18 and 34 approve of the players' actions. Among voters 65 and older and white voters, nearly two-thirds said they disapprove of the NFL protests.

The New York Times reported on Wednesday that Republicans now view the NFL more negatively than Democrats view Fox News, in light of the protests.

Voters also view Trump's personal qualities negatively. While 61% said he is a strong person, 56% said he isn't honest, 59% said he doesn't have good leadership skills, and 67% said he isn't level-headed.

And voters panned Trump's handling of key issues. Only 38% approve of how he is handling US foreign policy, and 39% approve of how he's handled immigration. Voters are more split on how he's handled the issue of terrorism, with 48% approving and 46% disapproving.
