Even Mayor de Blasio’s pals at Hot 97 are laughing at his now-defunct presidential campaign, and for good reason: The latest fund-raising numbers show what a complete joke it was.

He only pulled in $333,045 over the last three months of his four-month bid, after raising $1.1 million in the first six weeks.

And at least three-quarters of his cash came from big donors — most of them, people plainly looking for favors from city government, or repaying de Blasio for favors already received.

That includes the local hotel industry and labor union, the Hotel Trades Council — big beneficiaries of the mayor’s war on Airbnb. (To be fair, it’s a family relationship: John Wilhelm, a national hotel-union big, was a key supporter of his cousin Bill de Blasio from the start.)

Even including contributions as small as $1, de Blasio only managed to attract 17,000 donors across the entire country — just 13 percent of the 130,000 he would have needed to make the third and fourth Democratic debates.

Forget about the mayor of New York City competing with the mayor of tiny South Bend, Ind.: He couldn’t even make it into the ring with Rep. Tulsi Gabbard.

Oh, and de Blasio still faces a federal investigation into use of his Fairness PACs to kick-start the presidential campaign, which has repaid them $75,000 but wasn’t legally allowed to borrow that much from them in the first place.

With just $43,400 left on hand, the campaign spent a bit more than $1 million in its short life. Most of that funded the mayor’s travel to early-primary states to address tiny crowds.

But de Blasio’s presidential run wasn’t a total loss: His son, Dante, who graduated from Yale in May, got a résumé-building job out of it, earning $650 a week from Aug. 1 through Sept. 16 as a policy analyst for the campaign — which also hired one of Dante’s pals.

Hey, if you’re going to sell City Hall access to fund a hopeless campaign, you can at least see that some of it helps your family and friends.
