Kasich is only taking away votes from Ted which is allowing Trump to get more delegates. 

 I mean Ted could got all Utah delegates tomorrow if he gets 50%, but Kasich might stop that. And then Trump will just continue to get more delegates. 
And Trump is right. If he gets 1,000+ delegates, and the majority popular vote, and misses it by 200, then it's wrong for him to not get the nomination, and that will cause a uproar on the GOP if he's robbed. It'll be very bad, and there really could be riots. This might be good for Hillary either way.
