Of course that would give Trump another chance to scream cheater at those actually understanding and following those rules he he'd been too cheap and lazy to learn and use. Even while he was using a different part of those same rules to garner about 25% more delegates than his his percent of the actual vote. He swiped them from the losing candidates through the winners bonuses the rule's have provided. Trump will likely have a couple hundred such delegates by the time this is over, but never even mentions that unfairness.
It appears this year the Cruz team is trying to work with some of the party people, rather than run them over. I know some will scream GOPe etc, but there are many hard working, loyal, Republicans that don't have Cruz or Trump as their first choice, that will work hard for the nominee, regardless of who it is.
On May 21, the State Convention take place, it will be interesting to see what the Cruz strategy will be for those 18 delegates. My guess is they will have a 13 or 14 person slate to allow elected officials to go.
