HOW CAN REPUBLICANS BE SO STUPID?

Here is a story of a former Bushie who is disillusioned. Finally. I read this kind of thing and think - HOW CAN REPUBLICANS BE SO STUPID?
Seriously. I know it seems condescending of me - but I do wonder - how could so many people have actually thought George W Bush was "one of them"??? - when he was so obviously a greedy punk frat boy.

I truly believe being Conservative is an expression of a mental illness - the main symptom being denial.
