You'll recall that obscene exchange he had with Nate Silver in which he in short order began attacking Silver as a "pinhead" and a "hack" and wrapped it all up by telling him to go Cheney himself.In other words, a classic wingnut. (On the segment following this, Bob Shrum observed that having to interview a nutcase like Ziegler was akin to being waterboarded.)Watch the video and you realize that Ziegler, like many wingnuts, actually occupies another universe: the Bizarro Wingnut Universe, where up is down, right is left, and heads are implanted in hindquarters. The special quality of this universe is that its occupants believe that any point of view other than theirs is an attack upon them. Any thought other than those that jibe with their peculiar take on the world is evidence of a "bias" against theirs.The interview is sprinkled throughout with examples of Ziegler aggressively complaining that any skepticism of the Palinoid POV is an example of "bias" against her. He's also a master of Calvinball -- moving the goalposts wherever he can find a place to erect the moth-eaten "librul media bias" banner. Mostly, he finds ways to evade answering Shuster's rather astute questions, at one point even resorting to a cheap shot against Barack Obama as a way of steering the discussion into the ditch.Fairly typical of his style is this exchange, after Ziegler has accused Shuster of "bias" for having asked (in the earlier segment) whether or not Zieg...
