Trump has only gotten 39% of the popular vote in states that have already voted. Even in states where he won, he usually won with a minority vote. I don't hear anyone carping about all the people that DIDN'T vote for him being disenfranchised by the system because their delegates are bound to Trump.
39% is a pretty common winning vote in all 3 way races. What’s Cruz’s average, 20-25%?
You're missing my point. If they are bound to Trump or Cruz is not my point. The point is trying to switch/steal/pay-off the delegates after the vote has been cast. Now you have voters who have voted & won delegates, which are then being stolen, in effect switching the intent of the voters' ballot. In my opinion, if you can change the results of an election after the votes are cast it is nothing more than a dictatorship or banana republic.
