I can answer that. I first came to AZ in 1995. Since that time it has seen monstrous immigration from California as the libs take it further down the spiral.
People say that this is an excuse. It is not. It’s the truth. Look at the growth of places like Bullhead City, Kingman, Lake Havasu City and the Burbs of the Phoenix/Tucson/Flagstaff areas. Most of those new residents came from either Mexico or California.
The ‘old timers’ (and bear in mind, most of AZ’s population was imported at some point otherwise the Tribes and a few others would be the only residents) that used to be the bedrock conservative base of the state are overwhelmed by straight liberals and Cali RINOs that hate the ‘regulation’ of Cali, but still want the ‘services and bennies’ they got there.
Clarification... “Straight liberals” meaning Hardcore libs. There are plenty of the ‘bent’ variety here too.
