This guy is nuts. Rule #16 provides for either proportional or winner-take-all state rules and they are bound to the candidate they represent. In the event there are delegates for several candidates in a state contingent, Rule No. 18 provides that the majority mix of delegates can’t force the minority to vote with them.
Rule #38 DOES NOT permit winner-take-all delegates to abandon their candidate on the First ballot. Rule #16 strips them of delegate standing if they try.
They can rewrite the rules before the convention.
