My understanding is that candidates cannot keep their delegates after the first ballot and that they aren’t permitted to trade them at all.
Many, many people are continuing to insist that Cruz is hated by the establishment, and that they will attempt to replace him with an establishment guy.
Too many are saying that if Trump doesn’t win it on the first ballot, then he won’t win it at all.
So, the only protection these two have is rule 40.
What I meant is that Cruz has not been able to install his shadow delegates as Kasich delegates; they would more likely favor Trump over Cruz if they saw Kasich as the VP. Cruz is trying to override the will of the voters with religious affiliation.
