2018 Arizona State Legislature election

The 2018 Arizona State Legislature elections were held on Tuesday, November 6, 2018. A primary election took place on August 28, 2018. Voters in all 30 legislative districts of the Arizona Legislature elected one state senator and two state representatives. The elections coincided with the elections of other offices, including for governor and the United States Senate.

Members to the state senate are elected from the same legislative districts as members of the state house of representatives; however, one senator represents the constituency, while for the house there are two representatives per district. In this election, each of the party leaders from both chambers retired, and were elected to different offices.

Early campaign
In June, a judge ruled that former state senator Don Shooter, who'd been removed from the chamber earlier in 2018, could remain on the ballot for the Yuma district even though Shooter briefly registered to vote in Phoenix.

Independent district 28 senate candidate Mark Syms, husband of representative Maria Syms, was removed from the ballot after a Superior Court judge determined that his petitions contained over 900 forged voter signatures. This followed reports that incumbent District 28 state senator Kate Brophy McGee was supporting house candidate Kathy Petsas.

The most competitive districts in the state included District 28, District 6, and District 18.
