With most politicians, you aren't privy to their thoughts and don't know what their motives really are, so all you can honestly go on is their policies. Since I don't know any of them on a personal basis, I base my like or dislike of elected officials solely on the policies they support.
By all accounts Jimmy Carter was also a well-intentioned man who did what he thought was right while in office, and everyone who knows him personally finds him likable and decent. So what? Good intentions and a pleasant personality don't change the fact that Carter was a lousy President. Similarly, Bush may or may not be a decent person, I can't say because I don't know the man. I can say that many of the policies he supported were terrible.

Do you want to tell me that Dick Cheney is a Rino?
