New Report Highlights Arizona as a Model for Redistricting Reform Nationwide

Cambridge, MA — Today, the Ash Center for Democratic Governance and Innovation, a research center at Harvard Kennedy School released “The Arizona Independent Redistricting Commission: One State’s Model for Gerrymandering Reform,” a new report detailing the lessons learned from Arizona’s innovative approach to legislative redistricting.


The report’s authors, Colleen Mathis, the current chair of the Arizona Independent Redistricting Commission (AIRC); Daniel Moskowitz, Assistant Professor at the University of Chicago’s Harris School of Public Policy; and Benjamin Schneer, Assistant Professor of Public Policy at the Harvard Kennedy School and Ash Center faculty affiliate, argue that independent redistricting commissions such as Arizona’s have been successful at fostering increased competition in individual legislative districts and promoting partisan fairness in the state as a whole.


“Arizona is a pioneer when it comes to independent redistricting. In 2000, the citizens voted to take this power away from self-interested legislators and implement a more fair, balanced and transparent approach to drawing electoral lines that helps level the playing field for voters,” said Mathis, who has chaired the state’s redistricting commission since 2011.


Compared to states that leave map making in the hands of legislators themselves, “Arizona has performed well in terms of the partisan fairness of its map,” added Moskowitz, whose research focuses extensively on redistricting and voting behavior. “In elections held since the last redistricting, the share of seats a party has won has tracked closely with the share of votes cast for that party.”


The report closely examined the impact the Commission had on the competitiveness of the state’s elections following redistricting in 2012 and found that eighty percent of state legislative districts in Arizona became more competitive using the AIRC’s maps. “More competitive districts,” noted Schneer, “help ensure voters have a choice at the ballot box between candidates from the two major parties.” And as the authors argue in their report, “when politicians face the risk of losing their seats, they may be both more responsive to the preferences of more of their constituents and more likely to pursue bipartisan solutions.”
