I suspect that you only see what you want to see. and that you have a need to see the candidate Bush as one who clearly articulated a Conservative position with compassion, as one who's ideas and commitiment to the Constitution overshadowed the lesser candidates, and as one who's support in the campaign came from those who the vast majority of Republicans.
It wasn't so.
Bush was selected because of his charm and eye appeal and after very careful background checks showed that the dirt on him, if any, couldn't surface. People liked him, but he didn't have much at all in the way of issue-based support.
Today he has dissappointed those who hoped he'd be Conservative.
