"Sex with Republicans is so much better. People wracked with shame and guilt are ripe for a really spicy pounding! And there's nothing hotter than somebody who'll do me at night and publicly condemn me during the day!" — The Kinsey Sicks, from I Wanna Be a Republican .

While nothing can top the sight of a closeted, soon-to-be-defrocked Florida Congressman bleating to be let into the Congressional page dormitory, a night of sizzling satire and sexy trash talk from San Francisco's own dragapella quartet The Kinsey Sicks comes mighty close. The sassy foursome's I Wanna Be a Republican comedy concert film opening Friday at the Roxie Cinema is a laugh-out-loud funny distillation of material the Kinseys have been mining and refining since the 2004 campaign. To appropriate John Cameron Mitchell's pitch for Shortbus, it's another great way to get through the last two years of Bush.

For those who have somehow missed the Kinseys' meteoric rise from a Castro Street corner to sold-out engagements Off-Broadway and in Vegas, these boys in dresses and beehives specialize in dead-on song parodies. The night I met them backstage at the New Conservatory Theatre for my old KALX radio show, they treated me to a pitch-perfect send-up of the love song from Titanic, "Why Does Celine Go On?" It was wicked fun, yet retained the sudsy bathos of the original. The new show features the brassy Trixie (Jeff Manabat) vamping her way through "I've Been through Parasites (But I've Never Had VD)" to the tune of "I've Never Been Me." Who would have thought that an STD could top bulimia or the Scarsdale Diet?

What sets the Kinseys apart from, say, HBO's Bill Maher and his

The Kinsey Sicks in I Wanna Be a Republican.

Bush-bashing "new rules" is their divinely lewd and street-gutter banter and stage bits, sometimes with audience participation. The group's songwriting dynamo, Ben Schatz as Rachel, recalls some of Divine's prime moments as the world's filthiest woman. Early in the show, Rachel, the only group member who doesn't shave her pits, sashays into the audience to recruit a semi-willing "victim" for her stage business around the sentimental ballad, "Why Can't We Fuck?" The guy Rachel yanks out of the crowd — young and lanky, with a sexy schnoz — winds up dancing with a full-stemmed rose between his teeth. Rachel lovingly taunts the lad, using the full power of her drag office. "I know why you came to this concert. You want me, don't you? Answer me, fuck-face!"

As the above exchange indicates, the Kinsey Sicks specialize in pushing the envelope of taste and tolerance, even with their sold-out queer audiences. You can see startled expressions and grimaces mixed with laughter as the dragapellas proceed through their list of revolting topics, from "bobbing for butt hairs" to "Dragon Lady Hilary Clinton," to Trixie's mock-solemn affirmation, "I'm a pro-choice Republican. We can't have any more of those back-alley abortions. I've been in back alleys, and believe me, nothing ruins the moment more than a mangled fetus."

Mix and match

The Kinsey Sicks' greatest asset is the sly way their drag personas mix and match: from Rachel's incendiary lewdness to verbal hijinx from Trixie and Chris Dilley's silly Trampolina. At the other end of the spectrum, group co-founder Irwin Keller gives his Winnie the circumspect, slightly prudish air of an old-maid librarian. In the low-key show-stopper "Clean," Winnie touts the joys of scrubbing the kitchen floor over sex.

I Wanna Be a Republican is enhanced by fluid camerawork, putting the film audience in the catbird seat, heightening the fun, and sharpening the view of individual personalities. This is definitely a film that benefits from being seen in the company of a crowd looking for an irreverent good time, and it's also funnier on a second viewing, when the anticipation of a saucy moment doubles the pleasure.

Devotees of queer song parody and outlandish comedy may spot influences of the late Michael Callen and his beloved Flirtations, or the brief run of the Jew Meat trio at Jose's Cabaret and Juice Joint. Like those groups, the members of the Kinsey Sicks manage the tricky feat of being both drop-dead funny and sexy, in and out of drag. And one of them is single!

Deft audience cutaways permit Bay Area filmgoers to spot friends attending the two marathon filming sessions at the Broadway Studios in North Beach. Director Ken Bielenberg and producer Alonzo Ruvalcaba have made good on their vow to concoct LGBT films "that don't suck," and in the process have given the Kinsey Sicks a showcase to rival the Margaret Cho franchise, producing a comedy concert that equals the best of HBO. Later this year, Bielenberg and Ruvalcaba will release their documentary look at the Kinsey Sicks on the road.

The Kinsey Sicks delight not only in lampooning the age of Bush, but also in taking some sneaky pokes at their own fans' sacred cows. "Do you want Democrats in office who will sodomize goats while worshipping Satan?" Well, do you?
