1. Michigan at large delegates are bound 14-3-3 for Trump, Cruz, and Kasich. The Congressional delegates are bound 1 each for Cruz,Trump, and Kasich. The delegates are bound on the first ballot. If nobody has a majority, then they are free agents.
2. County Convention precinct delegates vote for delegates to state conventions. His county uses a secret ballot. Other counties use slates and floor votes.
3. State delegations vote for RNC delegates. Every district is different. He expects a favorable delegation for Cruz in his district as a lot of the activists in his area support Cruz.
4. As far as "will of the people goes" he said that the will of the people is split among several candidates. He's not going to rig it for or against Trump or anyone else. "The precinct delegates vote for state delegates and state delegates pick RNC delegates. If others don't like it, they can run for precinct delegate. They could have run for it in 2014 if they thought it was that important."
That is indeed the bottom line.
What we have is a bunch of complainers who are ignorant, arrogant, and lazy. And they seethe with anger at everyone except themselves.
Guess what, people who show up at neighborhood meetings and STICK TO IT up the line eventually get their way.
