He can't run for Governor again. He's limited to two terms, and he used up 8 months of his second term galavanting around the country. If he wants to run for Governor again, he has to wait another four years, but by then, Floridians will be saying "Ron Who???"
Or he can do what 3rd world countries do: have his wife run for office (wink-wink, nod-nod) then run again after her term is over.
