WASHINGTON, D. C. - Joe Biden. Elizabeth Warren. Bernie Sanders. Pete Buttigieg. Kamala Harris. Any of the top five Democratic candidates running for president in 2020 would beat President Donald Trump if the election was held today, according to a new national poll from Quinnipiac University in Connecticut. The poll looked at the overall vote, not the electoral college breakdown.

The poll of 1,422 self-identified registered voters conducted over the past week found Trump’s level of support is stuck between 38 and 40 percent, largely because his support among white women has deteriorated. Unless Trump can recoup his edge with that voting group over the next 14 months, the pollsters said that vulnerability “does not bode well for him.”

Trump campaign communications director Tim Murtaugh was skeptical of the poll’s findings, noting that none of the Democrats have ever been in a campaign against Trump and many of them are “largely undefined well more than a year before the election.”

“In November 2020, it will be a binary choice between President Trump and his clear record of accomplishment on behalf of Americans, versus whichever big government socialist the Democrats put up,” said Murtaugh. "President Trump will be re-elected.”

Trump’s job disapproval rating rose from 54 to 56 percent over the past month, said the poll, which has a 3.1 percent margin of error. Sixty-two percent of the voters it surveyed said Trump is dividing the country as president, while just 30 percent said he’s doing more to unite the country.

While 61 percent of those surveyed described the economy as excellent or good, for the first time since Trump’s election, more voters described the economy as getting worse than said it’s improving. Quinnipiac University Polling Analyst Mary Snow blamed the eroding economic confidence on trade tensions with China.

In the Democratic primary, the poll found 32 percent support for Biden among Democratic voters and those who lean independent. Warren was next with 19 percent backing, followed by Sanders with 15 percent, Harris with 7 percent and 5 percent for Buttigieg. Entrepreneur Andrew Yang had 3 percent support, and no other candidate had more than one percent.

The poll didn’t show any support the sole Ohio candidate in the race - Niles-area Democratic Rep. Tim Ryan.

Biden also had the edge in a hypothetical matchup against Trump: 54 percent of the registered voters the poll surveyed said they’d back the former vice president, while 38 percent said they’d support Trump.

The pollsters said Sanders would defeat Trump 53 to 39 percent, Warren would win 52 to 40 percent, Harris would beat him 51 to 40 percent, while Buttigieg would win 49 to 40 percent.
