Hours after apologizing for lecturing public-radio reporter Karen DeWitt about sexual harassment, Gov. Cuomo held his birthday fund-raising party — with ex-President Bill Clinton as the star guest.

Oops. The only act more tone-deaf would’ve been giving a shout-out to Bronx City Councilman Andy King, who’s dealing with misconduct allegations of his own.

Democrats nationwide are rushing to get ahead of the post-Weinstein avalanche of sexual-misconduct allegations. They’ve rapidly pushed out one senator and two House members without waiting for due process, and some have even expressed regrets over their 1990s defenses of Clinton.

But they’re finding it hard to throw Bubba, with his continued fund-raising prowess and large crowd of loyalists, completely under the bus.

New York’s own Sen. Kirsten Gillibrand has made “believing the women” her core issue. She led the carefully orchestrated denunciations that forced out Sen. Al Franken, and she’s even continued standing by the Columbia University “Mattress Girl” long after the woman’s claims were totally debunked by her own text messages.

But Gillibrand wound up having to partly walk back her slam of Bill Clinton. After she said he should have resigned the presidency over his intrinsically exploitative affair with a White House intern, Clintonite Philippe Reines slammed her for ingratitude — noting that the Clintons helped her rise to her current high office.

And Gillibrand dutifully backed off — clarifying that, if the nation had today’s awareness back then, Clinton’s conduct would’ve been inexcusable. Got it?

It’s still not clear if Gillibrand thinks we should believe all Bill Clinton’s accusers. Cuomo and most other Democrats plainly don’t, or they’d be shunning the ex-prez — not partying with him.

On top of this, New York Democrats still have to come to terms with the Albany payouts and coverups surrounding harassment and even rape of the Sheldon Silver era.

Zero tolerance isn’t as easy as it seems.
