If Cruz and Kasich were to use their heads....
It's neither necessary nor necessarily desirable that either withdraw from the race. But they do need to work together instead of at cross-purposes.
There are states- California comes to mind- in which Cruz is strong and Kasich is weak. There are others- Pennsylvania, for example- in which Kasich is strong and Cruz is weak. Why not each throw their support to the other in states in which they have no chance, but the other might beat Trump?
