Fallen ex-Gov. Andrew Cuomo is getting much more support than Mayor Eric Adams in a hypothetical head-to-head Democratic primary race for City Hall in 2025, a stunning new poll released Tuesday claims.

Of those Democrats with an opinion, 44% favored Cuomo to 24% for Adams with one-third undecided, according to the survey conducted by American Pulse & Research Polling.

Cuomo led Adams among all racial groups and especially among women.

“Our American Pulse survey revealed what I found to be a big surprise: If Andrew Cuomo ran as a Democrat for mayor, he would decisively trounce Mayor Adams in a primary,” said Dustin Olson of American Pulse Research & Polling.

“While surprising, it does make sense, as New Yorkers also gave Mayor Adams the distinction of being the most unfavorably viewed politician among all those we tested in the city.”

A recent Marist poll also found Adams’ popularity had nose-dived amid the migrant crisis, an FBI fundraising probe and proposed budget cuts.

The poll — which was paid for by a group headed by Adams’ 2021 GOP opponent, Curtis Sliwa — also found that 57% of all voters had a favorable impression of lefty Democratic socialist Rep. Alexandria Ocasio-Cortez, the highest of elected officials mentioned in the poll, while Adams had the worst unfavorable rating of 58%.

But the exiled ex-governor — who resigned from office in 2021 amid accusations of sexual misconduct — would lose were he to challenge Sen. Kirsten Gillibrand in a Democratic primary the next year, the survey said. 

In that match-up, 49% of Democrats preferred Gillibrand — who is up for re-election next year — to 35% for Cuomo in a Senate primary match-up.

Gillibrand clobbers Cuomo by more than 40 percentage points among white Democrats, while the former thrice-elected governor and former state attorney general led to a lesser extent among black and Hispanic voters.  

Cuomo has upped his public profile this year as he attempts to claw his way back to relevancy — hosting a podcast, speaking at churches and political clubs.

On Sunday, he was spotted having lunch at Junior’s restaurant with former Brooklyn Democratic leader Frank Seddio, a source who forwarded a photo of the two said. 

Meanwhile, the poll found 40% of voters oppose “illegal immigration and [believe] New Yorker tax dollars should be spent on New Yorkers, not for housing undocumented migrants.” It also found that 35% support a candidate who supports New York as a sanctuary city.

The survey conducted 417 interviews via live and automated phone calls and text/web online responses from Nov. 30 to Dec.1, and has a margin of error of plus or minus 4.8 percentage points.

A group called Save the Senate, chaired by Sliwa and aimed at bolstering the GOP in the US Senate, helped finance the poll.

The Adams campaign slammed the poll as a partisan job that involved his 2021 GOP rival, Sliwa.

 “This is a poll paid for by a group headed by Mayor Adams’ Trump-supporting Republican opponent in the last election, who opposes the Mayor’s efforts to help working families, reduce crime and protect a woman’s right to choose,” said Adams campaign pollster Ben Tulchin.

 “It’s simply not credible,” the Adams rep said.

Meanwhile, a spokesman for Cuomo referred The Post to recent comments made by the former governor defending Adams, and dodging a question on whether he would run for City Hall if Adams doesn’t seek re-election.

“I have not heard anything that would suggest that Mayor Adams has done anything serious,” Cuomo said on Fox 5’s Good Day New York.https://www.fox5ny.com/video/1311278

Cuomo said “we should stand with the mayor” absent evidence of wrongdoing.
