Cruz has been fighting for delegates who are truly loyal to him while Trump has been AWOL, leaving his delegate selections to the local GOPe. I would be shocked if Trump cleared 600 votes on a second ballot.
If Cruz did win the nomination with his dirty tactics, he won't have us to vote for him.
So don't whine about Hillary getting elected, you guys made a choice to run a scorched earth policy and Trump supporters will be gone.
Cruz will never be elected without Trump supporters votes.
Of course the GOPe could care less, since they are happy with Hillary and will regain control of the Party apparatus after using Cruz as their tool.
