RE: I think it will be Rubio (yes Rubio is NBC) although I prefer Martinez.
You are going to have a whole host of FReepers who will disagree with you here regarding Rubio being Natural Born.

Martinez is virtually unknown outside of New Mexico. If she is being seriously considered, she better be preparing hard—whoever is announced will be hit with an onslaught as least as ferocious as the one Palin faced, and he or she had better be ready to handle it.
