A longtime Wall Street corporate lawyer announced Monday that he’s challenging state Attorney General Eric Schneiderman in this November’s election, charging that the two-term Democratic incumbent has done little to weed out crooked Albany politics.

“My real mandate is to clean up the corruption in Albany,” Republican Manny Alicandro, a Brooklyn-born political novice, said outside Federal Hall in Lower Manhattan.

He added that Schneiderman has filed more than 100 lawsuits at taxpayer expense against the Trump administration and the federal government while being “totally invisible” when it comes to taking on the Buffalo Billion scandal and other Albany corruption.

He also charged that Schneiderman is turning a blind eye to problems plaguing the Metropolitan Transportation Authority and the New York City Housing Authority.

“I think people are fed up with the status quo of [Gov. Andrew] Cuomo just running roughshod and Schneiderman just rubber-stamping everything,” said Alicandro, who also hopes to land the Conservative and Reform Party lines.

Alicandro enters the race at a huge disadvantage — both in name recognition and campaign funds. As of January, Schneiderman had $8.5 million in his war chest.

“We expect to raise enough to stay competitive,” said Chapin Fey, a spokesperson for Alicandro’s campaign.

“Mr. Schneiderman’s liberal national profile has caused a lot of disaffection among Republicans in New York and across the country and with Manny’s finance contacts, we will be able to be competitive — even if we can’t match him dollar for dollar.”

State Conservative Party chairman Michael Long said he believes Alicandro can pull off an upset and alleged that Schneiderman spends more time quietly maneuvering to someday run for governor than doing his actual job.

“Manny is not a career politician,” Long said. “I think people are tired of all the photo ops and people looking to better their position. I think Mr. Schneiderman is looking to be the governor of the state.”

Julian Fox Spector, Schneiderman’s deputy campaign Manager, responded: “We’re proud of Attorney General Schneiderman’s record of protecting New Yorkers from Washington’s radical agenda, and welcome a debate with anyone whose stated goal is to appease and accommodate Donald Trump.”
