I may be giddily optimistic but I think the polls will be against Rubio in Florida and Kasich in Ohio, causing them both to drop out rather than be embarrassed by a loss in their own states. I think Cruz is well poised to win in Michigan, my state. No way will Kasich do well in Michigan.
Rubio is getting crushed in his home state polls right now. Yesterday they held an event in Jacksonville which was widely publicized and attended by a tepid response.
I would not count Kasich out in Ohio, I think he has a pretty good base of respect there. The real race, albeit it is a winner take all, is whom finishes second between Cruz and Trump as they will split the insurgent outsider vote there. I doubt Kasich gets 50%.
