Bernie Sanders’ campaign says it has gathered the signatures of 85,000 Democratic voters to qualify for the April 19 New York presidential primary, far exceeding the 5,000 required.

“It’s an astounding number,” said Sanders’s election lawyer Arthur Schwartz.

The mountain of signatures shows that the Vermont senator and Brooklyn native intends to run a competitive race in the Empire State against Hillary Clinton, the former New York senator senator and Secretary of State — should he remain viable after primary contests held in two dozen other states.

“We got tons of voter signatures in Brooklyn. There’s a lot of enthusiasm. Bernie absolutely has a shot at winning New York,” Schwartz said.

The Clinton campaign declined to say how many signatures it has collected.

The deadline to submit them is Thursday.

Sanders will certainly be considered the underdog in the New York primary.

Clinton has the backing of virtually the entire state Democratic establishment: Gov. Cuomo, Sen. Charles Schumer and Kirsten Gillibrand and Mayor de Blasio, among many others.

Following a press conference at City Hall Wednesday, Sander’s supporters will march by the New York Stock Exchange before dropping off the petitions at city Board of Elections headquarters.

Among the few politicians backing Sanders are state Sens. Bill Perkins of Harlem and James Sanders of Queens. Both are running for Congress this year.
