Not a lie, sparky
4 Colorado Senate Republicans who are party insiders and Cruz supporters changed “the rules” to abolish the election. It was a slick planned move and there was virtually nothing the voters could have done about that.
The people voted. They elected representatives to choose delegates. Trump’s campaign botched the conventions.
The rules weren't "changed" to "abolition" a primary election. There was no "primary" election in place. There was a non binding election in place. The establishment RNC created a national party rule that said that all non binding elections should be abolished. It was the establishment that wanted the change. It was the local conservatives who didn't want an Open Primary, who didn't want the change.
The four conservatives on the local Colorado Senate Appropriations committee balked at the idea of a binding primary because the bill required that the primary be an Open Primary.
It was the conservatives in Colorado who stood up to the RNC and to the local Colorado Democrats and RINOs. And this all happened in April and May of 2015 before Trump had announced. The August 2015 vote by the CO GOP was just an affirmation of the national RNC rules that they were required to uphold, because of what they decided back in April and May of 2015.
