You have to have a majority of the delegates to win the primary. Something Trump and his supporters don’t feel should apply to him.
Cruz seems to think that since he can't win the majority, it is alright for him to do what he can to stop Trump from doing so.
The primary system was set up to prevent convention fights, not lead to them!
The convention is only suppose to come into play when there is a true division like in the case of Ford and Reagan.
Cruz is way behind Trump and will be further behind at the end of the month.
