Yes.
As of October 2025, Arizona had more than 1.6 million registered Republicans on its voter rolls, a record high for the state.
Arizona’s electorate has expanded across all political affiliations, not just within the Republican Party, according to the Morrison Institute for Public Policy at Arizona State University.
Over the past several decades, the state has worked to increase access to the ballot through online voter registration, motor-voter laws that allow citizens to register to vote when obtaining or renewing their driver’s licenses, and early voting. Those efforts, along with population and economic growth, have helped boost voter participation and registration overall. Arizona’s population has climbed from almost 750,000 in 1950 to more than 7.6 million in 2025.
