Being a die-hard Bush supporter (and let's face it - is there any other kind?) is much like joining a fraternity. You go through Hell Week (9/11), and after that, it's just too difficult to break away. You've already defended the frat when that pledge died of alcohol poisoning, and during that massive cheating scandal. Then there was the bonfire that burned down the dorm - I mean, who could have predicted that would happen? Nothing will shake your faith in your brothers - nothing. So when two girls are raped after a keg party, no matter how much evidence piles up against the frat President and his roommate, you deflect. And defend. And never admit so much as a speck of culpability for the Prez, or anyone in the fraternity. If you did, your whole world would crumble around your feet. And nothing - nothing - will make you turn against this organization you've staked so much on.
Which explains why, if President Bush slit their grandmother's throat on national television, people like Dean Esmay would clutch her gurgling body and declare, for the cameras, that she had it coming.
