The best description of George Walker Bush ever penned (or at least for the next 48 hours which is forever in internet time):

Dubya is a white-knuckling, emotionally dead dry-drunk halfwit with the attention span of a massively over-caffeinated mayfly who believes in all the fun, flight-suit-related bits about being Preznit and leaves the hard thinky stuff to Dick.

There is no one better who skewers the modern conservative than driftglass.
