Biden was his scrappy-yappy-blabby self in the debate. I trust he is smart enough to reign it in if engaged in international situations requiring diplomacy. If he matched your ideology you see him as "real" and a little funny. If you have another ideology, you see him as annoying or something negative. What Biden didn't do? Bland himself down to a polished, typical politician who tries to pander to everyone and lacks being genuine.
Ryan: polished and slightly endearing, but lacking substance and specifics. But then - he doesn't match my ideology, so that's how I view him. Oh, and he has pretty eyes. Darn those handsome conservatives.
