On Arizona Public Media's Political Roundtable this week: Pima County Democratic Party chairman Jeff Rogers, Republican strategist Sam Stone and Tucson City Councilman Steve Kozachik tackle the U.S. Senate race between Democrat Richard Carmona and Republican Jeff Flake; the state Senate race between Republican Frank Antenori and Democrat Dave Bradley (including Frank's recent comments regarding the Tucson Chamber of Commerce, Jim Click and Don Diamond); the state House of Representatives race between Republicans Ted Vogt and Todd Clodfelter and Democrats Bruce Wheeler and Stefanie Mach; the state House of Representatives race between Democrats Mohur Sarah Sidhwa and Victoria Steele and Republican Ethan Orr; the Pima County Board of Supervisors race between Democrat Nancy Young Wright and Ally Miller; and the Board of Supes race between Democrat Sharon Bronson and Republican Tanner Bell. The panel was unimpressed with the "Pima Bunch" web ad series sponsored by the dark money campaign of Arizonans for a Brighter Future.
