Trump voters are not going to vote for Cruz if he 'wins' a convention fight, after staying in the race just to throw the race back to the convention.
This violates the spirit of the primary system!
If Cruz supporters think they can win without Trump supporters, they are more delusional then I thought they were!
And you can flip it around: If Trump supporters think they can win without Cruz supporters, who are insulted and vilified here in just about every thread--well, good luck with that. And if Trump thinks he can win by insulting, alienating, and blowing off social conservatives--again, good luck, Donald!
