Depressing, but perceptive.
Rove's forte is the "double-bind" -- the sexual double-bind where he implies his opponent is gay, the racial double-bind where he claims his opponent has fathered a black child out of wedlock, the forgery double-bind where he plants phony documents about real Bush scandals on a real journalist, so the forgery cancels out the scandal (and the journalist).
Rove feels like he's getting thrown under the bus

(or under the airplane) via the Plame investigation -- so maybe he just decided to keep his mouth shut and let Bush hang himself on this one last crony-incompetence deal too far, figuring Portgate could be a chance for the rest of the Republicans to distance themselves from Bush now that he's a lame duck with approval ratings stuck at 33 points below where Clinton's were during Monicagate. So the neocons might as well throw Bush under the bus now to start distancing themselves from him.
(Note that I don't think Bush "took one for the team" -- I think he's too arrogant to do that now, he probably thinks he runs the country or something. If you don't constantly prop Bush up for a couple of weeks, he'll slit his own throat. He is one of the most laughable figureheads in the history of the world -- "Great British" indeed. Just leave Bubble-Boy in his bubble for a few weeks and he'll fuck up quite nicely on his own. This Dubai thing is messy, but at least now Frist and DeLay can step forward and try to pretend they're serious statesmen, while the powers that be look for another Cheney-type to actually run things, and a pretty-boy with a sexy accent to be the front guy after Bush.)
Nothing "real" happens in DC anymore -- it's all a stage show for the rubes back home glued to the tube. A few people on the web know what's happening, the rest don't have the time to keep up with all the scandals.
But the bulk of the population, lulled by the lies of Tweety and Pumpkinhead, have never heard of a Rovian double-bind or Straussian secrecy or even Machiavelli for that matter.
