Well, one of the defining characteristics of Dubya's presidency has been stubborn defiance long past the point of wisdom, followed by complete reversals.

Consider:
- Starting a homeland security department
- The nomination of Harriet Miers
- The "resignation" of Donald Rumsfeld
- The 9/11 commission
- The CIA leak and pursuit of it

It seems to just be how he rolls.
