“Fargo” actor Steve Buscemi is among the donors who gave the maximum $2,800 to Mayor Bill de Blasio’s struggling presidential campaign.

Buscemi, a fellow Park Slope denizen, also helped de Blasio’s mayoral re-election race in 2017.

Politically-connected lawyer Frank Carone and his wife Diana each donated the maximum amount. Carone represented developers Stuart and Jay Podolsky in a real estate deal with the city that netted the brothers $30 million above the appraised price for 17 buildings in the Bronx and Brooklyn. City Comptroller Scott Stringer is probing the transaction.

Four other members of Carone’s law firm, Abrams Fensterman, gave $2,800 each.

Several lawyers with another firm, Paul Weiss, kicked in contributions. That firm represented public housing residents who won a $3.24 million settlement against the city in 2015 over the NYPD’s stop and frisk practices.

Another top donor was de Blasio’s cousin, Stephen Briganti, who is president of the Statue of Liberty – Ellis Island Foundation. He coughed up $2,800 to his kin.

De Blasio has raised just under $1.1 million from 6,700 donors since he launched his quixotic campaign in May, putting him toward the bottom of fundraising totals for the crowded field of 20 Democratic candidates.
