Idk there's a lot of Democrats in Texas, where they have art, craft breweries, and big yards. Naw, it's politicians that are sorting the people into just Republican or Democratic zones; changing the shape of the zones to cover where their people are such that it comes out that there are more Republican zones, thus making it appear like states are more "red" than they really are. When zones are picked by reasonable boundaries, then the Republicans say "see, Democrats are unfairly picking their voters, too!"
