Ordinarily, I'm wary of the "everything you know is wrong" article. Almost any time anything happens in our world and a conventional, obvious wisdom emerges, you're never more than two clicks away from an article on the Internet telling you why the opposite is true. If some candidate makes a horrific gaffe and plunges in the polls, someone will pen a piece that will explain that while this may look bad for that candidate, it is actually a bit of brilliant strategizing that has guaranteed his/her election in a landslide. I'm all for examining all possibilities but most of these articles seem forced and contrived and usually intended as attention-getting, separate-yourself-from-the-herd exercises.
That said, it is worth considering this article by Dahlia Lithwick, whose premise is that Alberto Gonzales did a great job with his testimony the other day.
