If Margaret Cho's act shows no signs of getting old, it's because the world is kind enough to provide her with sufficient lunacy to fill countless concert tours.

The stand-up comic's latest outing, "Assassin," was recorded in May in Washington, D.C., and most of it feels as fresh as a broadcast of "The Daily Show With Jon Stewart."

When it comes to politics, many comedians play it safe and don't take sides. Agree with her or not, Cho, to her credit, speaks her mind. She is fiercely outspoken in her attacks on the right -- defending gay marriage and the morning-after pill -- but her show never turns into a sermon. Her biting and incisive humor ensures that.

"Well, that's convenient," she says, taking on the media's love of the red-state, blue-state divide. "Now we have a color-coded map to where all the stupid people are."

In a lighter moment, and adopting a Valley Girl accent, she jokes about Christian fundamentalists: "Even satanists are saying, 'Wow, you guys are being really mean.' " One of Cho's best lines comes at the expense of Gov. Schwarzenegger and his "orange" perma-tan. "He's in some kind of Bain de Soleil web of despair," she cracks.

No joke is too raunchy and irreverent for Cho -- one routine involves the first lady and Lysol and a sexual act that won't be described here -- but more often than not her humor rips into the hypocrisy of the high and mighty.

"Queen, please," she says in mocking the pope, whose luxurious lifestyle, she points out, includes being surrounded by men at all times. "You live like Versace."
