After having seen Kerry in action, I am throughly convinced that he is a major asshole. I am also convinced, however, that Bush is a danger to this country and everything it stands for. I would rather have a jerk as the president than suffer political chaos and the persecution of minorities.
I think these three websites cover it pretty well:
www.johnkerryisadouchebagbutimvotingforhimanyway.com
www.twofacesofbush.com
www.bushin30seconds.org/finalists.shtml
Honestly, I won't be drinking a beer with senator Kerry anytime soon, so I am not so worried about the 'likeablility' aspect of things.
