Why Krugman Can Write

It's sentences like these: "The politics of stupidity didn't just appeal to the poorly informed."

Krugman works because he's continually outraged at how idiotic the public discussion is.

Sometimes he's so preoccupied with this that he loses it -- like, in my opinion, when he turned Obama's recognition of the problem with mandates to purchase health care (juxtaposed with Krugman's knowledge that mandates will probably be necessary to ensure universal coverage and bring costs down) to a full-blown conspiracy theory about Obama being a crypto-conservative cynically "attacking from the right."

But when it works, it's glorious.
