These are not attacks against Bush, these are attacks against his father.
"These are not attacks against Bush, these are attacks against his Father"
You hit the nail on the head with that one. Sounds like some sort of repressed hostility toward his father- and maybe his mother too. It's his way of getting back at his father for real or imagined emotional injuries. He probably never felt connected to his father b/c they are so different. After the attention he's getting wanes, he will probably feel even worse about himself. (Arm chair psychologist now taking off "shrink" hat)
