I use Paul Krugman’s international economics textbook, and I generally liked some of his criticisms of the Bush adminstration during the first term. But he’s gone, as far as I can tell, completely bonkers. [...] As an academic or at least a former academic, Krugman has at least some vague duty to try to be analytically coherent. But he has fallen into the habit of creating categories (fine) and then desperately trying to shoehorn available data into them.

Since Krugman has not been showing even fake evenhandedness for months now, I suppose this disclaimer should count as a step in the right direction. And what are the examples of "venom," anyway? Oh right, he doesn't have any, other than the obligatory reference to David Schuster's stupid comment about Chelsea Clinton.

What is Krugman talking about? I'm not sure why so many people were worried about hiring a professional operative like Bill Kristol as a Times columnist when it's Krugman who is so clearly in the tank.

Ouroboros alert! Paul Krugman took to his increasingly ironically titled blog to bring you a live shot of the next (not-quite-as-great) unraveling. Unfortunately, it's Krugman's hand on the thread.

Yes. The media meme that Krugman helped...uhm...pimp, is starting to worry him. Funny how that works.
