I'm going to go ahead and jump in with my two cents about Steven Colbert's performance at the White House Correspondent's dinner. You can see the video here, and Atrios has hightlights here.
First of all Colbert is balsiness personified for entering the vipers' den and refusing to pull punches.
That being said, what the hell were they expecting when they invited him to speak? Methinks the geniuses in DC don't get the joke that is The Colbert Report. It's easy to get lost in the jocularity and over the top bloviating, but if you missed the way in which he eviscerated both Michael Brown and Caitlan Flanagan earlier this month, then you clearly have no idea of how lethal Colbert can be when let loose among the stupid, the cowardly, and the hypocritical. Or rather, you didn't, until now.
