Did a little research....
As property values in California have steadily increased to near pre-2008/recession levels, migration from CA to AZ has also steadily increased as Californian's look for lower priced housing and lower taxes (a double bump up to the standard of living). However, AZ is fourth on the list behind Nevada, Oregon, and Idaho with Alaska and Washington right behind AZ.
This has also had the effect (not just to Arizona but to Nevada, Colorado, and Texas) of steadily eroding Arizona's historic Republican majority.
This is why we see Nevada as a mostly Democrat-leaning state now along with legal pot and increased gun control laws in Colorado.
It seems that behind entertainment, aerospace, and agriculture, liberals are now one of CA's biggest exports!
You're welcome.

Just a few facts mixed in with some humor and irony, which to the best of my knowledge (which has been questioned numerous times just this morning by my wife), are still legitimate literary styles. However, if you own one of those yellow Boxster's with the green leather interior, I make no apology and still think it looks horrible.)
