I have been saying this for weeksTrump will not be the nominee. The convention will be brokered. Kasich is the seasoned vet here, and where some have discounted him he's stayed the course, knowing exactly where he wants to go.
Kasich's goals is not to go in with the most delegates. It's to go in with more than Cruz if possible, or at least be close enough with Cruz to have negotiating leverage. If he does, he likely becomes the nominee. And if he is nominated, he defeats Clinton in November. If not, we get four more years of Democrat occupancy in the Oval Office.
Kasich needs to win PA & CA - both are very possible
If he does, he becomes the "compromise candidate"
He is our (by our, I mean republicans) best candidate, but Hillary is very vulnerable, I think even Trump can beat her
But I have been a Kasich guy for 20 + years...
