The bad news is that Jon Stewart isn't all that funny anymore.
The good news is, he may be the best serious interviewer on television.
I don't know of anyone who has been better or more consistent than Stewart when it comes to cutting through the bullshit as these ex-Bush administration officials do the talk show circuit to promote their books.
These days I watch Colbert when I want to laugh. But I'm more apt to watch Stewart interview a guy like McClellan than I am Tim Russert or one of the other Sunday morning talking heads.
