Replication Data for: Independent Commissions are Associated with More Competitive Elections

Competitive elections are essential for democratic accountability, yet most U.S. House elections are uncompetitive. Using district-level data from 1982 to 2018, I examine the relationship between redistricting institutions and U.S. House election competition. I extend Carson et al (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%.
