Blas, Cuo in summer slimeshare

The continuing blizzard of subpoenas demonstrates that New York’s twin corruption scandals are no mere spring fling. Investigations are expanding in the offices of both Mayor de Blasio and Gov. Cuomo and could make for a very hot summer.

Coming after numerous lawmakers were convicted in separate cases, the probes paint the era as one of the most corrupt in history. How’s this for a slogan: More crooked than Tammany!

Things are so bad that Mayor de Blasio is using Al Sharpton as a character witness. The mayor made a visit to Sharpton’s headquarters and again painted himself a do-gooder caught up in a witch hunt. “The voices of the status quo find many, many ways to undermine progress,” he claimed.

Sharpton echoed the “woe is us” tone, calling de Blasio a man of “integrity.” He should have found a word with less baggage.

Recall that the mayor had called Sheldon Silver a “man of integrity” when Silver was charged in the federal case that saw the former Assembly speaker sentenced to 12 years in prison and hit with nearly $7 million in fines and restitution. And this Thursday, another alleged man of integrity, former GOP state senate leader Dean Skelos, gets sentenced for his thievery.

Silver and Skelos are Cuomo’s former amigos from three-men-in-a-room infamy, and now the governor himself could be under the feds’ microscope again. Prosecutors want records showing whether six current and former members of his inner circle did anything to “benefit” 20 different companies that got state business.

Cuomo and de Blasio are sworn enemies, and each is no doubt happy to see the other in a jam. For now, both would be wise to hold the laughter.
