The system is rigged. This will cause a popular outrage among the Trump supporters and only help Trump win the required 1237 delegates the regular way and win on the first ballot.
The system is rigged against Trump, so he'll win? I think there's something wrong with part of that reasoning.
Isn't it more, just the gang bang? Trump's problem is that all the others with delegates want to stop him. That is less true of Cruz, at least with the Rubio faction. If team Rubio had Trump as the consolation prize, then it would have been Cruz that was burned.
