The other day I was contemplating a Mitt Romney/Jon Huntsman ticket. Of course, the GOP won't put up a two mormon ticket, but I think it would be a strong ticket. Republicans would still vote for them (over Obama) and they could pull a lot of moderate/Independent votes.
I'm really curious whether they will be smart and united with their selection or if the ultra-conservative elements will be completely unreasonable and reject any candidate who is relatively moderate. If they put up someone who satisfies the Tea Party, I don't think they'll have a chance.
