Believe All Bidens?

Bits and pieces of confirmation keep rolling in for Tara Reade’s accusations against Joe Biden, but Speaker Nancy Pelosi clearly voices the view of the Democratic establishment when she declares it a “closed issue.” Pelosi explained on MSNBC: “I have said I am proud to support Joe Biden for president. I believe him when he says it didn’t happen. But I also believe him when he says let them look into the records, and that’s what they should do.”

And: “I’m not going to answer this question again.”

Never mind that Biden is blocking efforts to look into his records, refusing to OK the release of his own files stored at the University of Delaware.

Or that, in a debate back in January, he slammed Mike Bloomberg for not opening his records when it came to coming clean about his harassment history, insisting, “This is about transparency from the very beginning. Whether it’s your health records, whether it’s your taxes, whether you have cases against you, whether or not people have signed nondisclosure agreements.”

The latest news: The tiny San Luis Obispo Tribune dug into the court records from Reade’s divorce back in 1996 and found that her ex-husband testified that she’d repeatedly discussed her experience being sexually harassed while working in thenSen. Biden’s office.

This follows the Larry King tape of Reade’s mom raising the issue around the same time, as well as various Reade family and friends confirming that she’s spoken privately about it all for decades.

Meanwhile, Biden has shown that the oldboy network matters to him more than even keeping up an appearance of sensitivity to the harassment issue, by tapping longtime pal exSen. Chris Dodd to lead his vice-presidential search committee. Dodd was one of Washington’s most notorious lechers, with the most infamous alleged assault coming in 1985, when he and Sen. Ted Kennedy (another lech-y Old Boy) reportedly manhandled their server in the “waitress sandwich” incident.

That woman, Carla Gaviglio, now 59, says she’s appalled Biden brought in Dodd — especially when Joe has promised to choose a female running mate.

“I think they should [have gone] a little deeper and thought about it. I don’t think it was a great idea and I think they could have done a little bit better. There’s so many people out there and why they had to make that choice is a little confounding,” Gaviglio told The Post.

Also meanwhile, Biden this week denounced Education Secretary Betsy DeVos for raising the burden of proof the feds expect universities to use in judging student sexual-assault allegations. Funny: By the standards Biden says he supports, he’s already guilty of what Reade says he did.

To be clear: Like DeVos, we’ve always believed that normal due-process protections should apply in these cases — the accused has rights, no matter how awful the accusation. The Reade-Biden dispute still boils down to he-said/she-said.

But Pelosi, Biden and the rest of their party claim that it’s not supposed to be that way when it comes to sexual harassment: Then it’s #BelieveAllWomen.

The most egregious squirmer is probably New York’s own Sen. Kirsten Gillibrand — who’s spent years aiming to be the most believe-ist of all.

Her laughable logic now: “When we say ‘believe women,’ it’s for this explicit intention of making sure there’s space for all women to come forward to speak their truth, to be heard,” Gillibrand said Tuesday.

And: “That is what Tara Reade has done. She has come forward, she has spoken and they have done an investigation in several outlets. Those investigations Vice President Biden has called for himself. Vice President Biden has vehemently denied these allegations, and I support Vice President Biden.”

In other words, it’s OK to wind up believing the man . . . if he’s your party’s nominee. All that thunder about standing up to powerful, abusive men was just noise.

Then again, Gillibrand also backed President Bill Clinton during the Monica Lewinsky mess. Only decades later did she change her mind, saying in 2017 that he should’ve resigned as president.

So: Expect Gillibrand to denounce Biden in about 2039.

What a pack of hypocrites.
