Kasich is now the man of the hour. Fresh off a good debate performance where he showed clearly that he's the adult in the room, Ohio is shaping up as THE key contest. If Kasich can win Ohio's 66 delagates, a path will be cleared to a brokered convention. If he loses to Trump, it's probably over and conservatism loses. It's imperative, it seems to me, for Ohioans who oppose Trump, even if Cruz or Rubio's their first choice, to unite behind Kasich to deny Trump a victory.
