There were no super PACs explicitly supporting individual candidates in the 2013 mayoral primary, officials said.
This mayoral election is different. Mr. McGuire’s super PAC has raised more than $4 million dollars from donors like Kenneth Langone, the billionaire co-founder of Home Depot; the art world philanthropist Agnes Gund; and the real estate developer Aby J. Rosen.
Mr. Donovan’s has raised more than $2 million, nearly all of it from his father. The super PAC for Mr. Stringer, a collaboration between Food and Water Action and New York Communities for Change, a social justice group, was just formed on Monday. It aims to raise a modest $50,000 to $100,000, using those resources to mobilize a pre-existing volunteer network, according to its treasurer, Sam Bernhardt.
Mr. Yang’s super PAC, Future Forward NYC, has only raised $35,000 so far, according to state records, though its founder, the entrepreneur and investor David Rose, said he aims to raise more than $7 million.
Mr. Rose suggested that the existing spending limit for campaigns that participate in the matching funds system — $7.3 million — was not enough to win a New York City mayor’s race.
“New York City is the single biggest market around, and to try to do a big campaign on quote-un-quote that kind of money is challenging in this media market,” he said in an interview. “My goal is to see if we can double that.”
Lis Smith, a former adviser to the presidential campaign of Pete Buttigieg, said she was also in the process of organizing a super PAC supporting Mr. Yang’s candidacy, aiming to counteract the bombardment of negative advertising that the presumptive front-runner is expected to face in the coming weeks.
