You mean evict all but the Utes? I had two friends from OK here 2 weeks ago, one is an Osage, the other Cheyenne Arapaho. They are the true natives, not the white folks with the 'native' bumper sticker. 
I've been in CO for 20 years and have been to more parts of the state and know more about much of the state than many of my friends that were born and raised in CO, several of which never go to the mountains and hate the cold and the snow. I love it all! 
Enough of the nativism. Just because someone was born in CO does not give them any more rights or privileges than anyone else. We are all Americans, some of us are native Americans.
