Democratic ex-Gov. Andrew Cuomo ripped the Dem Party on Sunday for letting physically and mentally feeble then-President Joe Biden run for re-election — before replacing him with a disastrous Kamala Harris.

Cuomo was jumping on the anti-party-leadership bandwagon as part of the fallout over a recently surfaced internal party autopsy of the Dems’ 2024 election debacle.

“[Biden] got on the debate stage, and it was obvious to everyone. You didn’t have to be a psychiatric or a medical professional to realize he was not up to the job,” Cuomo said on WABC radio’s “The Pulse of the People” show.

“Where was everyone? Where was the Democratic Party? Where was the chief of staff?. Where were his strategists? …The man was incapable of doing another four years,” New York’s former top pol said.

Cuomo’s comments come after a controversial draft of a report commissioned by the Democratic National Committee about the election was released last week — and put the blame on Biden allies for failing to get the party to rally fast enough behind then-Vice President Harris as its candidate.

The draft by former Bill Clinton strategist Paul Rivera notably didn’t even mention Biden’s own clear mental and physical decline.

It also failed to address Minnesota Gov. Tim Walz being picked as Harris’s eventual running mate or the shift in the party when it came to Israel after the Oct. 7, 2023, massacre. 

Rivera did knock the Biden team for not conducting polling before having him drop out and not doing enough to counter Harris’s ineffective resume as “border czar.”

Cuomo ripped the report as “disingenuous.”

But he also added that “it really cast doubt on the Democratic establishment — and rightfully so,” while calling out Sen. Chuck Schumer (D-NY) and other Democratic lawmakers and politicians who met wth Biden during his obvious decline and said nothing.

Cuomo, a recent failed mayoral candidate, suggested that party leaders covered up for Biden, pointing out how they kept saying publicly that Biden was “full of energy” and doing “push-ups” and “jumping jacks.”

“Come on, you fooled nobody,” the former gov said.

He did agree with Rivera about Harris failing miserably as Biden’s “border czar.

“The border policy was terrible,” Cuomo said.

When Harris he took Biden’s place at the top of the ticket, Americans only really knew about her border issues, he said.

“What’s the federal government plan? There was none. That’s not addressed. What did the Biden-Harris administration do for the country? That’s what it’s about. … [Americans]  want results. That’s what they didn’t get,” Cuomo said.
