Buchanon has his own demons that extend beyond Bush, but isn't it interesting how the people Bush defeats seem to go mad.
The Democrat Party in Texas seems to hold the strongest bias. They visited Kinko's to create false documents about his service. The Washington establishment of the party is in full meltdown. Gore is screaming himself horase. Kerry is running over the world playing president. General McCain wants to determine who will be Secreray of Defense, even though Republicans rejected him in 2000. I have no idea what Richards and his other opponent in Texas are up to these days, but I'd be surprised if they still weren't imagining "what if".
It must be because they form opinions of him before they meet him or really find out much about him.
I can't imagine any person not liking him when they meet him unless they were predisposed to resent him.
Maybe it's because he doesn't put on a show of the hard work, discipline and moral steadfastness that is the reason for his accomplishments. He makes it look easy and people misinterpret it to mean that he just got lucky or was "anointed" or some other excuse for him doing better than them.
