Unfair tactics by the RNC against Trump

Since Trump plays by his own rules and does not follow the RNC as a puppet, like the rest of the Candidates. The RNC has been systematically been playing behind the scenes to make sure neither Cruz or Trump will win. Example: In Tennessee, the State republican party is picking the delegates that are not trump supporters. They are bound on the first vote to vote for Trump but not on a second which is more likely to happen. So if Trump or Cruz do not win, then Trump the outsider, Cruz "The Tea Party" guy, could lose to Kasich or another establishment candidate. Why do you think Kasich is Still running, even though he only won 1 state, you need 8 to be considered on the second vote? The RNC can during the convention, can change the rules before the convention starts.... Nice. What's happening is the few deciding for the rest, very un American act, and if it does come out his way shame on them, a political revolution, where any non establishment will win.
