Not that random. Colorado is a blue state. Also, while I'm not a Coloradan, I've been there like 7 or 8 times and my brother went to college there. I've hiked, biked, done wilderness challenges, skid and snowboarded there and met many Coloradans in the process. You get the sense (backed up by articles like this:
http://www.bizjournals.com/denver/news/2015/11/19/colorado-voters-worried-about-climate-change-ok.html) that it's one of those places where a higher-than-average number of people on the right worry about climate change. They want to preserve their state and you don't have to have been there to know why. In terms of natural identity of America (i.e., pertaining to nature), Colorado is like a poster child.
