That’s not true. Hispanic turnout is 50%. Only half of legal adult hispanics vote. The Arizona statehouse is full of white conservative men. Brewer only gets 30% of the hispanic vote and wins comfortably.
Republicans get 66%-80% of the adult white vote in Arizona and Texas which is why those states are red. If every single Adult hispanic voted maybe that would be a closer election. But if that happened you’d have every single white voting to try to stop Rep Grijalva trying to ban guns and civilian border patrol.
Flake has always supported open borders and mass immigration. He was selling the amnesty in 2006 and 2007. His primary opponent ran ads where Flake said he is against Border Security first. They still elected him. You can look up old video of him on Lou Dobbs arguing with a conservative Republican.
The difference with McCain was he voted against the 2010 lame duck amnesty that Lugar and Murkowski voted for. That was 55 votes for the amnesty. If McCain, Snowe, Collins, Brownback and Graham had voted yes there would have been the Dream Act amnesty. After the backlash of 2010 McCain thought he was part of the movement.
If McCain crokes Brewer ought to send Wil Cardon to senate to trash Flake.
Brewer is far too progressive to do anything fun like that.
