Republican candidate for Arizona attorney general Mark Brnovich has released a 60 second radio ad highlighting his career as a prosecutor.

The ad titled, “who would you trust?” features Maricopa County Attorney Bill Montgomery contrasting Brnovich’s experience trying “hundreds of cases” with his opponent Democrat Felecia Rotellini who, Montgomery notes, “has never taken a single criminal case to trial.”

The radio spot will run in Phoenix and Tuscon and insiders tell me exclusively Brnovich will be up on television in the coming days.
