So the rule change was planned to allow an insider like Cruz to take advantage of them. Is that your idea of a democratic way to vote. Just created rules to your selection only. To hell with the voters, just work a corrupt method of winning. Wow! You're great.
You cannot prove or verify what you say about the rules change.
It was not changed to benefit any particular candidate.
Cruz had people on the ground that understood Colorado’s rules and used them to Ted’s advantage.
It’s called The Art of the Deal.
