Arizona State Senate President Warren Petersen holds a clear edge in trader consensus for the Republican nomination ahead of the July 21 primary, reflecting his institutional profile and name recognition in a race centered on electability against Democratic incumbent Kris Mayes. The contest with military attorney Rodney Glassman has featured pointed exchanges over legal experience and qualifications, including a May debate that turned personal, alongside recent campaign finance reports showing Glassman with stronger cash reserves. A late-June poll indicated Petersen ahead among decided voters but with a large undecided share, underscoring how endorsements, turnout in the final weeks, and messaging on defeating Mayes in November could still shift momentum in this low-information primary environment.
