Look at what you just said. President Bush is vindictive and cares more about his own ego and winning, than principle and the good of the country. If that's true, it speaks little for his character and surely such a person has been undeserving of conservative support all these years.
I'm praying your wrong and the President's character is far better than you give him credit for.
You'd be surprised at the supposed Bush-lovers' low regard for the man they love. I've heard the meme that Bush plans to appoint the worst possible person post-Miers, out of spite, for weeks-- by pro-Miers folks trying to shout down anti-Miers folks. It's crazy.
