If I had a nickel for every time he complains about something being unfair I could afford to retire and live at the lake full time. The rules are what they are and he needs to get off his derrier and get organized and stop whining. Even Bernie, who is being royally screwed out of delgates by Hillary doesn't complain half as much as Trump does. I can't imagine he calls for whining in Art of the Deal. I suspect he probably talks about knowing the rules of the game and playing them better than the competition. That's what he needs to do if he wants to win the nomination.
Speaking of which, he is apprently now predicting he will get to 1,237 delegates by May. I have read a number of analyses, the most optimistic of which is Nate Silver's, and there is no way he will get there by May or even by the convention. He has to realize that the rules state that the nominee must get at least 1,237 delegate votes at the convention in order to win the nomination. So far he has a total of 743 delegates and the remaining 875 were won by the others with Cruz being the closest at 545. He keeps talking about how he has millions more votes but that is only incomparison to his closest opponent. The fact is that millions more have voted for someone other than him. He needs to get to work to convert those delegates to him because Cruz is working on this diligently as he should.
