Doonesbury Say What?

"I don't think Obama has much fun. I mean, he hasn't hung around people who enjoy life. He hangs around people who are, you know, enraged and angry and ticked off all the time -- from his college professors on down to his terrorist buddies."
-- Rush Limbaugh

I would love to see Obama sue his ass off for making publicized statements like that. Yes, there's the first amendment, but there's also laws against libel and slander.
