I was looking through UT precinct results in DRA today and found this:
Biden won 4 precincts in the city, which is quite an impressive performance. The three precincts next to each other are in downtown, which makes a certain amount of sense. The fourth is by BYU, though it doesn't have the university proper--why does this area vote Dem when other spots nearby continue to vote Republican? Does it have bunch of non-Mormon professors or something?
That precinct has a large number of BYU students. It was also very strong for McMullin in 2016, and the precinct immediately north of it, which consists almost entirely of BYU dorms, was McMullin's strongest precinct in the whole country.
