I expected to click the link and see The Onion logo at the top of the page, not the Huffington Post.

This is clearly a joke, and while parody and sarcasm are not completely out of place in an opinionated-but-basically-factual context like HP's, the writer should have been a little more explicit in explaining that he was just kidding.

That said, I enjoyed the piece ~ especially the bit about William Kristol, W's adoring lapdog apologist to the very end!
