Independent Redistricting Commissions Are Associated with More Competitive Elections

Abstract

ABSTRACTCompetitive elections are essential for democratic accountability, yet most US House of Representatives elections are uncompetitive. Using district-level data from 1982 to 2018, I examine the relationship between redistricting institutions and election competition. I extend the work of Carson, Crespin, and Williamson (2014) by separating independent and political commissions and find that, relative to legislative redistricting, independent commissions are 2.25 times more likely to have competitive elections, and they decrease incumbent party wins by 52%.
