A day after launching his independent run for mayor, Andrew Cuomo spoke out to NY1, criticizing himself for losing last month’s Democratic primary to Zohran Mamdani.

But in an interview in his boyhood Queens neighborhood with NY1 political anchor Errol Louis, Cuomo also heavily criticized Mamdani, saying he’s “repulsed” by the Democratic nominee’s policy proposals because he doesn’t think they’re realistic.

“I did not run a good campaign. I admit it. And it was very uncharacteristic for me because all my life, I’m too aggressive, too difficult, too hostile, so tough and then I run a very nonaggressive campaign,” Cuomo admitted during an interview with NY1 in his old neighborhood, Holliswood, Queens.

Cuomo uncharacteristically showing humility, saying his double-digit Democratic primary loss to Mamdani was his fault, after he and top aides got too confident reviewing polling in his favor.

“That was a mistake and playing it safe was a mistake and again uncharacteristic,” he said. “There was no inspiration to it, there wasn’t enough positivity to it.”

Cuomo said he checked the right boxes on the campaign trail, discussing affordability and public safety plans, but he didn’t foresee younger voters coming out in droves — and rejecting his candidacy.

“It is a younger generation, very upset about what is happening in this country and beyond. Socialism, why? Because this doesn’t work. ‘So let’s try socialism,’” he said, imitating his view of younger voters’ mentality.

Now, he’s changing his strategy by meeting New Yorkers in the streets and angling for a full-court press against Mamdani.

“I think the assemblyman would do damage to New York. Not just that, I don’t agree. I believe it would actually damage New York. And I’ve been having this battle with the socialists for years,” he said.

Mamdani spokesman Jeffrey Lerner responded in a statement, saying, “It’s no surprise that a man who’s being backed by Donald Trump is repulsed by the notion that working people deserve a city that puts them first.”

Having a history of sparring with the left, Cuomo angered Democrats by perpetuating a years-long alliance with the Republican-held state Senate.

He also nearly eliminated the Working Families Party after it backed his 2018 primary opponent.

On Tuesday, he rehashed old battles.

“This is the Amazon project. I work for a year to get Amazon to come to New York to open up a national headquarters, 25,000 jobs — the socialists oppose it and wind up killing it,” he recalled, referring to the Amazon project that would’ve put a massive site in Long Island City, Queens.

He slammed tax hikes as the answers to funding Mamdani’s proposals.

“They’re anti-corporate, they’re anti-business. New York is about business. There is no future for New York if you are going to be anti-business,” he added, saying Mamdani’s promises are unrealistic.

“So to now throw out these three word solutions: Freeze the rent, build grocery stores,” he said. “I’m repulsed by it.”

He’s pledging to drop out if he’s not polling as the top candidate against Mamdani by mid-September.

“If Eric Adams is stronger as a candidate, God bless him. I’ll step aside,” Cuomo said.
