Cruz and Kasich are under strong delusion if they think there is going to be a convention battle.
They both, along with the vast majority of the GOP were doing everything possible to have a convention battle. It would appear that will not happen, or if Trump is not at the magic number, he’s going to be so damn close it can’t be taken away. If he fell a couple hundred short, it could have been done. but he’s already there with a number of states to go. I don’t think anyone at this stage expect the nominee to be anyone other than Trump....maybe a slim light of hope that California would slip away or be a tie and a few other non-Trump wins that counter the Northeastern dominance last week. I don’t think anyone has high hopes at this stage that Trump loses, even if they fight these final battles with vigor.
