Yeah, that's a bit over the top.

About the only realistic thought I have as far as not just writing him off, is this: it's not inconsistent for someone who believes in the death penalty if he believes Bush is guilty of (some death penalty worthy crime).

I don't, for 2 reasons:
1) I've come around from my earlier beliefs, mostly. Life is a gift which despite any misuse we have no business taking away. I used to view the death penalty as the ultimate deterrent: dead people don't commit crimes. But it's possible to deter without this.

2) I think he's made some poor decisions, but I hesitate to even think of any as possessing that level of criminal intent.

But that's about it, and it's really tenuous.
