The political landscape in Arizona could be on the brink of transformation as Republican lawmakers propose an early redrawing of legislative and congressional districts. This move follows a recent U.S. Supreme Court decision prohibiting states from using race as a predominant factor in district mapping.
Sen. Warren Petersen, a Republican from Gilbert, intends to initiate legal proceedings to revise the state’s district maps, citing the Supreme Court’s ruling in Louisiana v. Callais. Meanwhile, Democratic Sen. Ruben Gallego suggests that such redistricting could advantage Democrats by potentially increasing their hold in Congress and the state Legislature.
“When it comes to the state House state Senate, I think the Republicans would probably lose the state House state Senate in perpetuity at that point,” Gallego remarked during a recent discussion. He elaborated on his previous attempts to adjust district populations to make them less Latino, arguing Republicans were concentrating their voters into fewer districts.
Arizona’s Redistricting Dynamics
The Independent Redistricting Commission (IRC) of Arizona, consisting of a bipartisan group, is responsible for drawing legislative and congressional boundaries every ten years. This commission, created through a voter-approved initiative, last met in 2021 to delineate the current districts.
Arizona’s congressional landscape includes nine seats, with a 6-3 split favoring Republicans. Similarly, the state Legislature’s 30 districts are currently under Republican control. Unlike other states like Louisiana, where the Legislature manages redistricting, Arizona’s IRC must adhere to both the federal Voting Rights Act and additional criteria, such as maintaining “communities of interest” and respecting municipal and geographic boundaries.
The Supreme Court’s decision, which particularly addresses Section 2 of the Voting Rights Act, complicates challenges against districting that might dilute minority votes. Professor Chad Westerland from the University of Arizona notes that this ruling may encourage some states to modify “majority minority” districts to benefit Republicans. However, Arizona’s unique political and racial distribution complicates assumptions about which party stands to gain.
Westerland highlights Tucson as a case study: its large Latino population is split between two congressional districts. Congressional District 7, represented by Democrat Adelita Grijalva, is solidly blue, while District 6, held by Republican Juan Ciscomani, is highly competitive. A redistricting that shifts Latino voters from CD7 to CD6 could potentially tilt District 6 toward Democrats without jeopardizing Grijalva’s position.
While some states prepared new district maps in anticipation of the court’s decision, Arizona did not. “The usual take has been, the absence of the Voting Rights Act will help Republicans in the short term,” Westerland explained. “That’s just not the case in other places where it’s going into where that decision is having an effect immediately.”
Petersen anticipates filing a lawsuit by year’s end, with new district maps possibly taking effect before the 2028 elections, subject to court and legal processes. Westerland advises observing Maricopa County, given its population density and potential for partisan district manipulation.
Overall, the impact of redistricting on Arizona’s political makeup remains uncertain. The IRC’s mandate to preserve “communities of interest” and the geographic clustering of minority groups, such as the Navajo tribe, might result in minimal changes to existing district maps.
