BIG BUCKS IN MAYOR BATTLE

Eric Adams, who received $4,388,102 for his mayoral run, came out on top, according to the city Campaign Finance Board.

“I am so proud of our campaign for reaching this fund-raising milestone — and for doing it the right way,” Adams (inset) crowed in a statement.

Comptroller Scott Stringer, who’s also vying for mayor, got a cool $3,330,535.

“We’re proud to be part of the most progressive campaign finance system in the country, and we’re thrilled with the momentum behind our grassroots campaign,” his campaign spokesman Cameron Hellerman said in a statement.

To qualify for matching funds — which come at a generous rate of $8 in taxpayer money for every $1 raised by a candidate — mayoral contenders have to raise at least $250,000 and receive contributions of no more than $2,000 each from 1,000 city residents. Only contributions from city residents are matched.

Other candidates in the crowdeed mayoral race tried to project cconfidence even though they ddidn’t qualify for matching funds iin the first round of the current ccycle.

“We will receive matching ffunds very soon!” said Yuridia PPeña, a spokeswoman for Shaun DDonovan, a former aide to Presidentd Barack Obama and Mayor Mike Bloomberg. “We opened our committee in February and stopped raising money when the city went on pause.”

Ray McGuire, who recently stepped down as an executive at Citigroup to run for mayor, opted out of the matching-funds program. He’s expected to raise big bucks from the city’s business community.

Maya Wiley, a former legal aide to Mayor de Blasio, did not return a request for comment.
