Video cameras. And alcohol. Wait, that's two reasons. Combine them. Drunk videotaping is the number one reason I will never run, or allow my husband to run, for office.
Check out this video of Joe Biden, supposedly drunk.
I think it's ridiculous that someone went through the time and effort to try to find this "damning" piece of evidence. As if being drunk and singing a stupid song disqualifies you from being VP. I mean, jeez...he's fully clothed, he's not doing any type of drug, and he isn't cheating on his wife. He's practically Jesus by political standards. Give the guy a break.
(P.S. I'm still voting for McCain)
