Trump could have played by the rules and won a large number of delegates without being a party insider. All he had to do was show up and care. He did neither. This is either a result of ignorance, indifference, or entitlement. Regardless of the reason, this should be a flashing red light that your chosen candidate isn't what's being advertised.
Instead of demonizing Ted or the party over a system that has been in place for decades, or in some cases more than 100 years, you should be questioning your candidate as to why he chooses to whine and hurl baseless accusations when he didn't even bother showing up. Like Trump said about the primary process: “Don’t forget, I only complain about the ones where we have difficulty.”
Who's not going to get the nomination - no matter what? Ted Cruz. Your candidate is the most hated guy in the U.S. Senate. No one likes working with him and he's not demonstrated a capability of working with others either.
As is, your candidate is nothing more than a useful idiot for the GOP-E to stop Trump and guarantee their survival. That's truth. Even Rush Limbaugh admitted it today and I've been saying this for months already, that when it came down to Trump and Cruz, the GOP-E would saddle up with Cruz then dump him at the Convention.
