In the 2022 midterm elections, state legislatures across the country were host to several competitive races. In Arizona, both the State Senate and the State House were battleground chambers. Before the election, Republicans maintained a 31-29 edge over Democrats in the Arizona State House, and the chamber was at risk of switching partisan control in the election. However, the result was status quo, as Republicans maintained their 31-29 advantage in the State House overall. This article will look at the districts with split partisan control, of which there were five.
