A Democratic club in Queens is snubbing veteran Rep. Joe Crowley by endorsing his primary rival, Alexandria Ocasio-Cortez, for Congress.

The Pan-American Democratic Association’s support of the insurgent is a double slap at Crowley, who is also the longtime chairman of the Queens Democratic Party.

“Ocasio-Cortez is a better representative of our neighborhood. She’s more progressive. She’s not behind the banks, insurance companies and Wall Street,” said William Salgado, chairman of the club, which covers Jackson Heights, Elmhurst and Corona.

First elected to Congress in 1998, Crowley hasn’t had a serious primary in 14 years. His 14th congressional district takes in parts of Queens and The Bronx.

Crowley, No. 4 in leadership in the House Democratic caucus, is considered a candidate to become the next Democratic leader and possibly House Speaker if Nancy Pelosi steps down.

Salgado said Crowley, 56, doomed any chances of getting an endorsement when he blew off a debate sponsored by his club at the Jackson Heights Jewish Center on Monday.

He said about 200 people showed up and many were disappointed that Crowley wasn’t there.

“Ocasio-Cortez showed up,” Salgado said. “A lot of people didn’t like that Crowley didn’t appear.”

Ocasio-Cortez, a former school teacher who is of Puerto Rican heritage, poses a challenge to Crowley in a district that is majority non-white and half Latino.

Still, Crowley remains the clear favorite to win re-election over the 28-year-old insurgent, who has the backing of leftist groups including True Blue NY, Our Revolution, Bronx Progressive and The People for Bernie.

Virtually the entire Democratic Party establishment is behind Crowley — though the Pan-American club’s abandonment is a break in the wall.

In recent interview on Intercept.com, Ocasio-Cortez said she was running against machine politics and said it was a “astounding conflict of interest” for Crowley to serve as a congressman and the county Democratic leader.

She also rapped Crowley and his family for living in Virginia instead of the district. Crowley has also a residence in Woodside.

Crowley campaign spokesperson Vijay Chaudhuri responded,: “We’re proud to have widespread support from the vast majority of Democratic groups in Queens and the Bronx, including the Jim Owls Liberal Democratic Club, the New Visions Democratic Club, and Queens Young Democrats.

“The Crowley campaign worked incredibly hard to make this event work. Unfortunately, the Pan-American Association scheduled and publicized their forum without inviting Joe and then refused to adjust the date so he could attend. Despite this, we offered, and were denied, the chance to send a representative. It is disheartening how the group handled this forum as Joe would have loved to participate.”
