I wish candidates chose running mates once they accepted the nominations. It's an important component and now we all have to research the proposed Veep and evaluate how they'll work together. So I have no opinion on Biden yet. I do wonder if "OBAMA BIDEN" on a ballot is going to look too much like "OSAMA BIN LADEN" to some folk, but I may just be too pessimistic about the average voter's intelligence.
(I'll try to change.)
