Outsider, and will appeal to the unity / Black vote..
Personally, as much as he is probably a nice bloke, I dont think he suits politics.
Similar to Kasich, I dont think Trump will go with Kasich given he is only really popular around Ohio, and he has a history with Lehman Brothers that almost brought down the world economy.
I know many dont think it will be Cruz, but if Trump is deadset anti-establishment, it has to be either Cruz or Carson??
Some more outsiders..... Newt Gingrich or Guliano?? They both support him.
