More here, in a commentary on a New Yorker article along the same lines.

The "progressives" are in intellectual fibrillation.

Link from Glenn Reynolds, who nails it:

^The thing to understand is, this article isn't about the Kochs at all. It's about preparing a narrative for the New Yorker's readers about why Obama has failed. It's not because they were rubes who voted for an underprepared, under-skilled candidate who then proceeded to alienate the electorate. It's because Obama was beaten by a right-wing billionaires' conspiracy so vast as to defy understanding. That's all. Relax, New Yorker readers. No need to feel bad about yourself for being overwhelmed with hope-and-change fever and voting stupidly. It's not your fault. It never is!^
