After 23 years in office, the notorious Maricopa County Sheriff Joe Arpaio (R) might not win re-election. The latest Arizona Republic/Morrison/Cronkite News poll of the Arizona county sheriff's race shows Arpaio nearly 15 points behind Democrat Paul Penzone, 45.9 percent to 31.1 percent. Arpaio, who calls himself "America's toughest sheriff," made national headlines last year when he spoke out in favor of Donald Trump and joined him in the mission to "seek the truth" about President Obama's birth certificate. Arpaio's massive slip is likely due -- at least in part -- to voters' widespread opposition to building a border wall and deporting all undocumented immigrants, both proposals Arpaio supports. The poll found that 30.8 percent of the county's voters strongly disagree with mass deportation, while 41.7 percent disagree.
