As ranked-choice voting (RCV) continues to spread across America, activists, voters, election officials, and state lawmakers want to know more about the effects of adopting RCV and other voting systems on participation, processes, partisanship, policy, and power. Recognizing the need for more—and more publicly accessible—research on electoral reform, New America's Political Reform program formed the Electoral Reform Research Group (ERRG) with partners at the American Enterprise Institute, the Unite America Institute, and Stanford University's Center on Democracy, Development, and the Rule of Law.This collection of ERRG research includes 15 original studies, presented here as a series of briefs. The full papers are available to download for free on the Social Science Research Network website
