1.There is a large Mormon population in Wyoming
Not especially large. Way smaller than Nevada, which is way smaller than Utah. Its largeness is more of a relative proposition.
Lumping Wyoming in with Idaho and Utah as the "Mormon triangle" is a common misperception, but a misperception nonetheless.
When the polls were indicating a big swing in Wyoming (not big enough to make it competitive or anything o/c) I liked to think of it as another Montana except without Butte and with far fewer Indians... then the polls were right in Montana but wrong in Wyoming. Oops.
I think the oil-impacted parts of Montana didn't swing nearly as hard as the remainder of the state though, so maybe I just should have added "and with more oil".
