This is a trial balloon to generate interest in Bloomberg.
Bloomberg will be the professional political consultant class candidate and his VP selection will be made by pros who will never consider HRC because of her negatives (and age). The selection will be made solely on polling.
Mark my words - the Bloomberg machine is going to do and float all kinds of stuff to generate interest in his candidacy for the next few months. Watch the coming shift in the media punditry class in the next month towards him - it is already starting.
