Do you in your heart of hearts actually believe that Ben Carson is not a political “dead man walking”?
I suppose he could be hanging in there with the hope of grabbing the VP slot, like Kasich.
Yes, I believe they are both in there as potential VPs.
I think Kasich also stays in because, if some establishment candidate sprouts wings, then if Kasich wins Ohio, he can deliver delegates and both block Trump and become an establishment VP.
