Trump and Cruz aren’t “picking delegates”.
I am volunteering to be a committed delegate for Cruz.
Fellow delegates as State Assembly determine whether I go.
All available information suggests a significant majority of our State Delegates to Nat’l will be committed Cruz.
That's why it is a good idea to have a ground operation in each state that knows what each state's rules are.
Also why Trump supporters are now starting to panic over the increasingly likely prospect that Trump will not win enough delegates to get the nomination before the convention.
