Um, that's everything...
One is personalizing 9/11 - which has pretty much been the agenda since, oh, about 5:00 pm on that day in 2001.
Two is selecting Cheney as his VP, and three is bringing Karl Rove into the White House.
I don't think it's hard to argue that every major (and probably every minor one, too) decision that has come from this administration has had either Dick Cheney's and/or Karl Rove's meaty fingerprints all over them.
So...in essence, this is a roundabout way of saying that every single part of the Bush presidency has been a mistake.
Hey, wait...that's my line!
