Trump isn't being 'denied' anything. He is blowing it, either by design or incompetence. The fact is, Trump is absolutely failing at setting up state organizations. He is winning a primary, then he just leaves. He is breaking his first promise- to be a candidate. This would be akin to him winning the bid for a building contract, then never actually building anything. Winning a primary doesn't mean you are done, it means your work is just beginning. You have to set up precinct offices and work with the local and state party to ensure you have a say in the delegates. This is also the infrastructure he would use if he wins the nomination to compete against Hillary. If he doesn't do this, he deserves to lose the delegates because he is breaking his promise to the voters to be their candidate. He can complain and cry all he wants, but the fact is, he is the one who is blowing it.
