An ample-bodied drag queen (stage name: Flotilla DeBarge) declared that âjust because itâs gay doesnât mean it thinks our way.â
A curiously masculine version of Tina Turner cried that New York City âdoesnât need another Bloomberg clone.â
But perhaps nobody summed up the eveningâs raw emotion and risqué tone better than John Cameron Mitchell, the actor and writer, who invoked an unprintable obscenity as he mocked the City Council speaker, Christine C. Quinn.
A rowdy and occasionally raunchy series of performances on Sunday night at a fund-raiser for Bill de Blasio, a Democratic candidate for mayor, offered a potent display of his support from the cityâs gay and lesbian community.
But, as much as anything else, it highlighted a splintering of the gay community in this yearâs mayorâs race, laying bare simmering frustrations with Ms. Quinn, who is gay, from parts of a voting bloc she has long symbolized and championed.
Much of the evening was given over to a biting critique of the Quinn era of government, which the actors on stage treated as synonymous with Mayor Michael R. Bloombergâs tenure in office.
The ill will toward Ms. Quinn was so great that the mere mention of her name drew catcalls and laughter.
At one point, the actor and writer Charles Busch belted out a sarcastic song, titled âYurtle the Turtle,â that depicted Mr. de Blasio as a noble frog challenging a cruel king (Mr. Bloomberg). Near the end, he paused for effect.
âI havenât even mentioned Christine,â he said, to loud applause.
A man dressed, unconvincingly, as Ms. Turner put an anti-Quinn spin on the singerâs hit song âWe Donât Need Another Hero.â
A sample lyric: âWe donât need another Starbucks. We donât need another Duane Reade. We donât need another bank branch - or a Bloomberg clone.â
The audience of 300 at the Cutting Room, a venue in Midtown East, roared.
A skit featuring the actors Stephen Spinella and Sarah Paulson touched on Ms. Quinnâs biggest political vulnerability: her vote to extend the cityâs term-limits law.
âIsnât a third term illegal?â Ms. Paulson asked mischievously.
At times, the evening tested the boundaries of taste.
Midway into the fund-raiser, a woman dressed as Reba McEntire took the stage, offering fictitious recollections of her high jinks with Mr. de Blasio.
âWe were tripping on acid, riding horses naked through my pastures,â she recalled, as she looked in Mr. de Blasioâs direction.
âI can say that?â she asked in mock horror, as Mr. de Blasio and wife, Chirlane, sat a dozen feet away.
In a closing number, the actress Bridgete Everette emerged from the audience, a glass of wine in hand, and sat on Mr. de Blasioâs lap, caressing his hair and bouncing on his knee as she delivered a halting version of a song she had written for the occasion.
âSo comfy and roomy,â she rhapsodized of the candidateâs knee. âFeels natural to me.â
As the laughter grew, Ms. Everette leapt off Mr. de Blasioâs knee.
âThat was tasteful!â she told the audience. âI did not do anything sexual.â
Afterward, a seemingly scandalized Cynthia Nixon, the eveningâs co-host and the former star of âSex and the City,â playfully assessed the political fallout.
âI donât think the campaign is ever going to recover from this evening,â she said.
Ms. Quinnâs campaign expects to attract much of the cityâs gay and lesbian votes in the Democratic primary this fall and has lined up its own list of boldfaced gay endorsements.
Still, members of the audience, who paid $25 each to attend the fund-raiser, were openly skeptical, if not hostile, to Ms. Quinn, saying that the gay community had moved beyond the moment when it needed to speak with a single political voice.
âShe has done a lot for us,â said Leslie Smith, who said he had worked with Ms. Quinn on gay rights issues in the past. âBut the race is bigger than her.â
After the show, Ms. DeBarge, the drag queen who sang a riotous version of âDonât Mess With Bill,â walked out of the theater into a packed bar area to accept her plaudits and explain her remarks.
âIâm supposed to like Christine Quinn because Iâm gay,â she asked, incredulously.
Asked whom she would vote for, Ms. DeBarge eyed a reporterâs Blackberry. âI see you typing,â she said, adding a curse.
âNo comment.â
She brushed by with a sigh. âI need a drink.â
