How Can We Increase Turnout among Low Propensity Voters

Abstract. How can we increase voter turnout among low-propensity voters? Researchers and practitioners have found interventions that increase voter turnout, but these interventions tend to increase turnout among individuals already likely to vote, and therefore appear to exacerbate existing inequalities in participation. This project developed and tested an intervention designed to encourage people with a lower prior likelihood of voting into the electorate. First, in summer 2018, we surveyed a diverse sample of voting and non-voting Californians about their political attitudes. We concluded that feeling inadequately informed and feeling inefficacious may contribute to low turnout rates. Based on the results of the survey, we designed messages to address these feelings and tested them in an experiment to increase turnout in two special elections in June 2019 by targeting these sentiments among people with infrequent prior turnout records. Letters with information and encouragement about the voting process did not increase turnout in the subsequent election. We conclude that further work is needed to identify interventions that successfully increase turnout among low-propensity voters.
