From this Friday evening's Countdown with Keith Olbermann:

Comedian Lewis Black, whose latest special is “In God We Rust,” sounds off on Rush Limbaugh’s role in the GOP’s war on women, Mitt Romney’s pre-existing pet problem and Rick Santorum’s anti-porn position. Black says he could understand if Santorum wanted to tax porn rather than getting rid of it, but concludes: “I don’t know what else he’s doing except wandering around, like, in the desert. It’s like having this weird prophet who’s kind of like in the wrong decade.”
