Arizona voters will decide Proposition 317 on November 3, 2026, a legislatively referred statute that declares drug cartels terrorist organizations under state law and directs the Arizona Department of Homeland Security to use all available authority against threats from groups engaged in drug trafficking, human smuggling, or related terrorism. Republican lawmakers advanced the measure via House Concurrent Resolution 2055 after Governor Katie Hobbs vetoed similar legislation in 2023, building on voter approval of the Secure the Border Act in 2024. Federal actions designating specific cartels as terrorist organizations have reinforced the policy focus on border enforcement. These factors, combined with the measure’s limited fiscal impact and alignment with existing state priorities on cartel activity, underpin trader consensus around a strong likelihood of passage in the general election.
