What is wrong with Arizona that a scummy politico like Attorney General Tom Horne is the state's top law enforcement official, while the most ethical prosecutor in the state will probably never occupy that position. The latter, of course, is Yavapai County Attorney Sheila Polk, a staunch Republican who does not let party or ideology get in the way of doing what's right. In 2009, during the darkest days of the sinister partnership between Sheriff Joe Arpaio and then-Maricopa County Attorney Andrew Thomas, she took a stand against the pair, referring to their antics as "totalitarianism . . . spreading before my eyes." Thomas was disbarred in 2012, in part because of the actions Polk decried. More recently, the campaign finance case against Horne landed in her lap, and she's ordered Horne and his henchwoman Kathleen Winn to pay back $400K in campaign contributions, despite Horne's winning an administrative hearing in the matter. Horne, Arpaio, and Thomas are all Republicans, but Polk's all about integrity, not party loyalty. We hope she runs for AG one day. But then, in Arizona, you almost have to be ethically challenged to win a political campaign, it seems. Sigh.
