The rules of the primary are clear. Just as many sports have overtime if no team has a win at the scheduled end, primaries are decided at the convention if no candidate has a majority of delegates before the convention. If Cruz is down by three and going for a three-pointer at the buzzer to put this game into overtime, that has been part of the rules for 200+ years. It’s a perfectly legitimate strategy.
Team Trump just has to block the shot that Cruz is taking. They are trying rhetoric to do that, but their argument is too weak to work. They have to stop Cruz at the polls, and they may be strong enough to do just that. They know the rules, and I’d like to see them outplay Cruz under the rules of the primary and if necessary of the convention.
Primaries are entered with the view that one man is going to be chosen to lead the Party by the voters.
Convention battles are for the purpose of dealing with virtual ties, as in the case of Reagan and Ford in 76.
The convention is not to be used as an alternative to the will of the voters, when one candidate cannot win the majority, but does what he can to stop the frontrunner from doing so.
So, stop trying to defend this nonsense.
