"They hate him for his very existence."
That's true, and the DEFINITIVE PROOF lies in the fact that Bush has many policies that have angered his right-wing base voters. He has increased Federal spending to record levels. He has failed to secure the border (which may change before the second term is up). You'd think he'd be hailed as a hero to liberals for spending so much on government programs designed to help the poor. But they hate him no matter what his policies are.
