FYI, neither Cheney nor Allan Simpson are native sons as neither was born in Wyoming.
Simpson’s father was a Wyoming-born Senator and Governor of the state. I don’t know how Alan Simpson happened to be born in Denver. From what I can tell the family was living in Cody at the time. It’s not like he moved there as an adult just to run for office. Cheney’s family moved to Wyoming some time before he started high school from what I can find out online.
