Of course not. No complaint about a winner take all based on a vote has been raised. People generally understand and accept that some states do winner-take-all delegates, and some do proportional delegates, and there are reasonable arguments for both systems of how to distribute delegate slots per people who see themselves as voting for candidates.
Cheating is when one candidate wins a delegate slot, but the delegate put in that slot is not loyal to the candidate that one the slot but is chosen by another or bribed.
I have confidence that most people that support Cruz would agree with this simple distinction, and only people who are feverish over the top supporters of Cruz would ask something so silly.
....that one the slot...
I simply don’t believe Colorado to be such an outlier that of the 65000 people that voted, not enough of them voted Trump to even be represented by one single delegate at the convention. There is something wrong with that picture.
