Cruze may take missouri.
That would only mean he’d need 850 of 1100 instead of 900 of 1100. To date Trump has defeated him in 2 out of 3 states and Cruz has taken about 28% of the delegates. Nothing in those numbers says he’ll run the table between now and the end. Any hope they have is for the party to take it away from the winner out of animosity and give it to one of the losers. If that happens they will lose to Clinton, because the anger will be insurmountable.
