The “unqualified lesbian” is on a roll.

Cynthia Nixon’s campaign boasted Thursday that the leftie actress collected more grassroots donations in a single day than rival Gov. Andrew Cuomo has in seven years — while a rattled Cuomo dismissed questions about Nixon’s fundraising might as a “small” issue.

The “Sex and the City” actress’ campaign said it raked in 2,214 donations of less than $200 in the first 24 hours after she announced her campaign Monday — compared to 1,369 Cuomo has reeled in since the start of 2011.

“Andrew Cuomo has built a $31 million war chest from wealthy corporate interests, lobbyists and billionaires,” said Nixon campaign manager Nicole Aro. “The incredible grassroots enthusiasm we’re seeing so far is a sign that Democrats know that we can do better than Andrew Cuomo.”

Asked about it at an unrelated press conference in The Bronx, Cuomo walked away from reporters while saying: “I’m going to go back and work on the budget, and then we’ll answer your small questions.”

Nixon has also been raising money off former Council Speaker Christine Quinn’s gaffe this week calling her an “unqualified lesbian.”

Democratic political operative Hank Sheinkopf said Nixon’s grassroots dough proves “she’s got support” but questioned whether the actress scripted the sudden torrent of donations.

“It’s a planned event to show a multi-millionaire actress is one of the people,” he said.

GOP consultant Ed Rollins quipped that “it’s the Bernie Sanders campaign all over again,” referring to the socialist 2016 presidential also-ran, who raked in small-time donations but couldn’t get the Democratic nomination.

The Nixon campaign said it could not immediately say how much it took in.

The 1,300 small donations to Cuomo’s campaign total just under $94,500 — a fraction of the $76.6 million he’s raked in over the seven-year period, filings show.

Nixon’s campaign has pledged not to take corporate donations, but it will still accept money from limited liability companies. Larger businesses sometimes create numerous LLCs to get around contribution limits, but Nixon’s campaign said it still won’t take money through the LLC loophole.

“Many small businesses, mom and pop shops, and small law firms across New York are legally classified as LLCs. We welcome those New Yorkers to join our campaign, but we will not be welcoming donations from corporations or the loopholes they employ,” said campaign spokeswoman Rebecca Katz.

On the campaign trail, meanwhile, Nixon continued hammering Cuomo over corruption.

“In the corruption Olympics that is Albany, I think Andrew Cuomo is winning himself some gold medals,” the actress told the Buffalo News.

Nixon also questioned the $420 million annual tax breaks that the state provides for film and TV productions — which have benefited her own “Sex and the City” series.

“I don’t think there’s any real truth that enormous expenditure of money is making a significant enough difference in production to justify it,” she said.
