George W. Carter
Andrew Sullivan hits on something that I've been thinking for awhile. Bush is Carter:

Both Gallup and CBS now have Bush at all-time lows in approval numbers; and the ratings for the GOP appear to be way below the water-line for November. Things can change. But I have a feeling that Bush has now become Carterized. It is very hard to see how he can regain his footing at this late stage. After six years or so, the public knows who you are; and they have come to a judgment.

It's a shame too, but you reap what you sow. I still like the guy though, and that bit he did with Bush impersonator Steve Bridges solidifies that. But he's just in over his head here.
