Arizona: Dispute arises from state query about election system | Tucson News Now
At present, 13 of the state’s 15 counties are linked into the state system, but the two counties each maintain their own voter systems and databases. Pima County recently spent $4 million upgrading and implementing its system. The Secretary of State is exploring the possibility of replacing the statewide system with a more modern platform. The Arizona system was one of two systems nationwide that was hacked last summer. Following an FBI investigation, it was thought to be by Russian hackers. During the investigation, the state system, as well as the 13 counties on the system, were shut down for a week. “Maricopa and Pima Counties were able to keep working, processing voter requests, processing whatever we needed to do,” said Pima County Recorder F. Ann Rodriquez.
