Granted that Jon Stewart now and again accidentally says something funny. But he and his supporters think that he's a high holy fool, speaking truth to power under comedic cover. In fact, he's not all that exalted or bright, and he really has no kind of perspective or thoughtful point of view on politics. He can be counted on to hold to standard issue reflexive knee jerk left wing positions. But he's an idiot as far as knowing anything or making any even vaguely serious argument.
This became even more apparent than ever on January 16, when he thought he was just going to sandbag Jonah Goldberg of the National Review, there to talk about his new book Liberal Fascism. You could tell that it had gone badly for Stewart by the disclaimer that he felt it necessary to run at the front of what he eventually broadcast. He explained that his interview with Goldberg ran 18 minutes, but they only have six to show it in. Sorry about the choppy editing.
First off, why couldn't he show 18 minutes? Famously, there's a writer's strike going on, and he's billing the whole show separately - A Daily Show, rather than The Daily Show. He could have lost that second section of the show entirely, just boring time filler crap. Hey, an actual substantive conversation! That's a decent substitute for scripted comedy.
Real obviously, Stewart tried to edit his way to victory with what he put on the air. He maximized airing his little petty mockeries while cutting Goldberg short, cutting him off mid-sentence, and such foolishness. Yet Brother Goldberg ended up without intentional derision making Stewart look the absolute most overtly stupidest I've ever seen. It's not Jonah's fault. He did not come out with malice.
