If the establishment can throw out any delegate that they choose then they can certainly insert insiders and D.C. types at the convention and shut out all forms of disagreements and dissent in 2016 and beyond and I’m not even talking about the antics of the Paulbots here
I agree that they “establishment” should not be able to throw out delegates, but I do think that the candidate himself should be able to throw out the delegates he won if they do not support him. Binding candidates through the first ballot makes since.
