Rubio will get trounced in Fla and may even come in third. Too bad that one is winner-take-all because I think it’s a lost cause (but you never know, that Sanders win in Michigan showed nothing can be taken for granted. Not this year.) Rubio dropping out will be a huge help to Cruz and should have been done a lot earlier. The best outcome will be for Cruz to come in a close 2nd to keep the overall popular vote close.
Kasich will likely take Ohio. If he does it will depend on if he is going for a brokered convention or if he is trying to stop Trump. To stop Trump Kasich must also drop out fast to consolidate people behind Cruz.
Once Cruz gets 1v1 with Trump he will crush him; then its a matter of delegate counts to the end.
