Here is a link (you may have to get past a “survey wall” to read it) mentioning that CO GOP officials are considering a traditional primary vote for 2020: http://www.coloradoan.com/story/news/2016/03/02/super-tuesday-leaves-colorado-gop-guessing/81157802/
“The Colorado GOP is already looking to make changes for the next presidential election cycle.
