Christie/Rubio. That combo would likely deliver Ohio and Florida. If you win both those states, the odds of winning the general election are over 90%.
One may not agree with everything Christie says or does, but he gets the message and it is better than Obama.
Give Rubio time to show that he really is as conservative as the TEA party that elected him. He makes RINO like noises every once in a while. We here in Florida want to see him live up to our conservative expectations before he goes anywhere else.
