My guesses:
Rubio. A Republican Enrique Inglesias. Women will love him. Is he Constitutionally eligible? Plus FL has a GOP gov. that would name a GOP replacement should the ticket win.
Randy Paul: A nod to the Ron Paul faction of voters. KY has a Rat gov. I think, so his replacement would be a Rat.
Huckabee: Mittens ain’t winning in the Southern Red states. Huck helps Milt out with that problem. Too bad Huck is a RINO.
Yes, don't listen to the nutbars who say he isn't.
Losing a Senate seat is not an option so Paul Jr. and any other Senator with a rat Governor can forget about it!!!
