Also, California has the most Republican voters of any state, there is no reason to assume the people leaving are mostly Democrats.
Still bring that bougie California BS w/ them tho.
Laramie county also has a big chunk of Democrats as it is a college town. ~6000 of that 7815 are the students and I assume most of the rest are staff members
