If some Democrat had spewed that line to Bush during one of his addresses to Congress, I'd say the same thing. Even with a dumbass like Bush, the office he held was more than the man that held it.
There's an old saying in the military; you salute the rank, not the man. Same goes for the prsident, you respect the office, if not the man in it. Joe Wilson clearly showed he has no respect for anything but his opinion of himself. In short, he's an asshole.
And the Republicans and conservatives have held him up as a hero. Their hero is an asshole. How apropos.
As for the GOP, heh, they're screwed. A majority of Americans consider themselves to be conservatives or moderate conservatives, and yet, the GOP has lost registered voters for the last 20 years, even as the general population claims to be turning more conservative.
The conservative party is losing members as the general population turns more conservative. I wonder why that is. Could it be because they're mostly assholes?
That's my bet. Most people don't like hanging around assholes, even when they agree with them.
