Nominally speaking, Trump should own a plurality of the Rules Committee and of the Convention body.
However, those "Trojan Horse delegates" are bound to Trump ONLY for the requisite number of ballots. They do not have to follow his lead in any other matter. And, indeed, are likely to resist his lead when it comes to something like disqualifying delegates from Colorado -- who were selected quite legitimately.
It is foolish and wrong for anyone to assume that they would resist going in favor of Trump once the duress is removed from them.
Delegates can flip both ways. And one who is so easily flips one direction may just as easily be flipped the other.
Unless somebody in the Cruz campaign stops the hemorrhaging, by the time the convention rolls around delegates pledged to him may be looking for a way out. The stench of his behavior is not playing well with middle America. We are on to you Ted Cruz!!!
How much you want to bet with Trump’s resources that most if not all the Fraud delegates are already identified and will be challenged for cause plus maybe charged with misrepresenting for money?
