Two points.
1) What are all these people moving in going to do for a living? It’s a desert. They might be able to take over the government, but there won’t be much to run. The county does have some tourism, but it also holds parts of 3 Indian Reservations, so they presumably don’t even really run the whole county.

2) Last I looked, my own heavily populated and fairly diverse county in the SF Bay Area was being run pretty much in keeping with the Constitution. I’ll bet wherever you live, your county is too. So why bother to move to Arizona to do it?
What a bunch of loons.
