Currently living in CO, but since the delegates no-longer represent my choices, I have to agree. Yes, exclude them.
I once lived in Colorado, and was there for 2 decades. The courts tend to like to override the voters votes, and obviously they don’t want any candidate competition. It’s a Cruz only race...so yes, Colorado hates their voters. Eliminate the expense and the circus that goes with it. It’s a dead state. Serves no purpose except to take up space and drain resources.
