Leading Off: ● Maricopa County, AZ Sheriff: Former Phoenix police Sgt. Paul Penzone is waging a rematch against notorious Maricopa County Sheriff Joe Arpaio after losing by a surprisingly close 51-45 margin four years ago, by far the worst showing of Arpaio's decades-long career. Now Penzone has released an internal poll from Strategies 360 that has the challenger leading the incumbent by a 48-44 spread, which KPNX's Brahm Resnick says "might be the first time any candidate has topped Arpaio in a public opinion survey in recent memory." Penzone's poll also asked about Arizona's presidential and Senate races within the confines of Maricopa, the state's largest county and home of almost 60 percent of its population.
