Utah County is obviously owned by BYU, with Utah making some inroads there the last ten years.

SLC is heavy Utah.

SL County is pretty evenly split, but probably leans a little Utah at this point given that they are the cool school still to a degree.

I think Davis Co leans BYU but not by a huge margin. Probably the same for other parts of the state.

20 years ago it was BYU everywhere in the state except for SLC. Even U grads pulled for BYU a lot because they were the only game in town. Now almost all U grads I know pull for the U.

State overall leans BYU I think but not be a wide margin like it did 20 years ago.
