Bush vs. Dean -- Bush is in the lead.
Dean has a lot of work ahead of him. Name recognition is important. As an image consultant, I suggest he yell a little louder next time, wearing a belly shirt and sporting a navel piercing. Here's a link to the Bush Nose Pick video.
Of course, no one would suggest not voting for a guy just because he picks his nose in public. Just as no one would suggest not voting for a guy who gets a little excited in front of his supporters and lets out a sympathetic farm rally yell.
