Well, Colorado WAS purple, 12 years ago, Obama changed that. It's been mostly blue with the exceptions of the rural fukk lands.
Colorado has a population probably 10x Wyoming, has multiple urban areas with cities over 250k. The metro part of Colorado (Springs to Ft. Collins) is for the most part very progressively liberal, Co Springs being the one iffy area. There are parts of Colorado that are barely populated just like Wyoming.
So what about that makes it like Wyoming? And, have you visited either state, if so, what parts?
