Yeah, I feel that if you try to create three Hispanic VRA districts in Arizona, you may end up with two conservative Anglo Republican representatives in most years.
Admittedly, creating 3 Hispanic-majority districts would probably be good for Grijavala, as he'd lose the South Phoenix area and Yuma area to the new district--the places he does the worst in. It would basically screw over Giffords however, as the 7th would have to bite into the Democratic-leaning precincts of Tuscon that keep her district competitive.
