Kasich can win every delegate form here on out and still not win the nomination. No one has attacked him yet, not even a little bit. If he took the hits that Trump has taken he’d already be done. If he gets to the general they’ll make quick work of him and if he wins the country will not heal
The only reason he's still standing is everyone thought he was too insignificant to bother with, and they're still thinking that. DON'T....he'll do whatever it takes.
