Here's a link to the full episode.
This was a completely brilliant show, and highlights everything that makes Jon Stewart so special. First his response to Bernie Goldberg and Fox. It was uncompromising and withering and hilarious, but at the same time self-deprecating... and it even managed to come off seeming evenhanded.
Then his interview with John O'Hara, a tea-party-er who wrote a book about the tea party movement. Again, Jon Stewart somehow walked a fine line where he was clearly polite and interested in meaningful discourse, but didn't let O'Hara get away with any crap. And, the whole time, the show remained funny and incredibly watchable.
Jon Stewart is the greatest populist political commentator working today.
