Yes, the old people in Maricopa county keep voting him in, for the most part. I actually worked on Paul Penzone's campaign (he ran against Sheriff Joe during the last elections - bet you have no idea who HE is, but of course you know who Joe is, because you pay attention to mass media, awesome, two thumbs up, good for you!). I am well aware of Sheriff Joe. As an Arizona-native and a previous 14+ year resident of Phoenix, which is in Maricopa County, I probably know more about him and his terrible reign than you do. But thanks for the unnecessary education!
But he's still only one small aspect of a pretty big state. Tucson, Tempe and Central Phoenix are pretty great places, and hopefully these places inspire more change in the state as a whole. And Flagstaff and Sedona both have a lot of pluses, although Sedona gets way too woo-ey for me. But still, fairly progressive towns.
Also, Medical Marijuana !
There is plenty wrong with Arizona, but there is still some good stuff going on and if they are lucky, the good will prevail.
That is, unless it burns up in a fiery ball of flame before that happens. Which is a possibility.
