Brewer felt she had to sign last week's immigration bill, because she felt Arpaio's breath on her neck. She had to appear as tough on brown people as Arpaio does, lest he decide to challenge her in the GOP primary.So she signed it. And guess what? Arpaio's still going to run against her. Sources in the sheriff's department, which will likely double as his campaign staff (no new thing there), say his paperwork's filed. And on his Twitter account - where you can read about his Washington Post interview today, or his "crime suppression/illegal immigration" operations briefings, or his anger about "out of town critics" - he recently tweeted that his wife wants him to run. And he's already the frontrunner in Arizona Republicans' minds.
So why not run? What does he have to fear? Latino turnout in the Phoenix metro area? Problem solved!
