Bush is already a known idiot and liar .. nothing new here.
But, the politician this will affect most is Clinton. It completely removes the facade of "experience." Her claim that her vote on the Lieberman bill has changed the Republican Guard is infantile and I'm surprised she would reach that far for an excuse. Can't use the old "I was tricked" excuse this time.
It makes her need to pick Obama as her running mate SHOULD she win even greater. Not too long ago she was ready to be annointed as the nominee as she ran away from everyone else, but this failure of judgement is going to last .. and it's going to hurt.
