Well, it is designed to be a system whereby a person who is active in the party (and friendly with a lot of people who are in it) gathers support and wins the nomination.
Now a completely out of it maverick could always win like Trump is trying to, by simply winning the delegates he needs on the first ballot.
If he has to rely on actual relationships with actual people who are delegates, he will probably be way underplayed.
Thanks, for explaining. It really explains how these old lifers are almost impossible to kick out. If nothing else Trump has made people actually look at our election rules and set up. Its much more involved than most think. (Me being one)
