Felony Disenfranchisement and Voter Turnout: Randomized Trials in Iowa and Washington

Prior to the 2022 midterm elections, we conducted large-scale randomized controlled trials in Iowa and Washington aimed at increasing voter turnout among newly enfranchised individuals with past felony convictions. Alongside national and grassroots partners, we designed and implemented experiments to ascertain the effectiveness of alternative outreach mechanisms, including targeted mailers and digital ads. We did not detect statistically significant or economically meaningful effects on voter registration or turnout; most observed effects were precise nulls. The absence of measured impact is likely attributed to low digital engagement with our online ads as well as extensive voter outreach already conducted by our local partners prior to the study. Our evidence highlights the importance of context in voter outreach efforts, as the political and legal environment in Iowa and Washington differed significantly from other regions where similar interventions had previously shown success.
