Even now there seems to be a remarkable degree of Not Blaming The Guy In Charge for all of the reasons he's unpopular. Katrina, Iraq, the Social Security debacle, the midterm elections are all sort of things that happened to poor George Bush, instead of, you know, stuff he was responsible for.
I know nothing is ever George Bush's fault, according to George Bush, but its rather miraculously how much that view has been universally adopted.
