Would anyone be opposed to returning Arizona to Mexico?
Yes. They're called "the Mexicans".
The Chichano nationalist would have a field day with this one
We are, of course, assuming a scenario where the Outer Phoenix Metro Whites* stay in place. Evidently, their deportation back to their points of last non-Arizonan origin would change everything.
*and Payson, Lake Havasu, Prescott etc pp. The rural Mormons may be voring for similar people but I suppose they could be allowed to stay. Heck, deport the rich hippies in Flagstaff and Sedona too while you're at it.
But that would mean Arpaio stays with us, no? How about we just deport Arpaio?
Nowhere else would take him, and why should they? You'll have to deal with your own trash.
The Golden Dawn types might take him; he proposes similar things to what they do (instead of landmines, electrified border fences, but still)
