A lot of it has to do with the fact that he is a mainstream economist who pointedly makes fun of the ideas promulgated by the Chicago School, Ayn Rand and the general sort of things you find at mises.org and other right wing watering holes.

I suspect most of his critics are the sort of folks who think that they would be billionaires if only their taxes were low enough and governments weren't so restrictive about things like labor laws and environmental regulations.

Yep, the problem with Krugman is that he only "makes fun" of opposing ideas (and not just in the realm of economics). As someone incapable of considering other viewpoints on their own merits and engaging them in good faith, he's not worth taking seriously as a columnist.

He's only one among many such types penning editorials for NYT.
