Well, I think we can safely count out Perry, Paul, Jindal, Gilmore, Graham, Santorum and Christie. They are polling very poorly and trailing in the polls.
Bush and Rubio will be players for the long run; the establishment as wells as the RNC will continue to back them. They are their only hope.
I think Trump, Carson, Cruz, Walker Huckabee Fiorina, will continue to rise in the polls. I'm no t so sure on Kasich.
