My prediction is that Governor John Kasich is not going to support Donald Trump if he gets the Republican nomination. I've been thinking this thought the last few days and I think I'm getting "official" confirmation of that tonight... CNN's Anderson Cooper asked Kasich if he'd support Trump if he were the nominee and he declined to answer. Basically he said, we'll see.
If Kasich does announce that he will not support Trump as the nominee, it will open the door to other establishment candidates to announce the same.
I hope Kasich understands that he will be destroying the party when he makes his announcement.
