Even before the 2020 election, this reseach finds that voter turnout across the states is consistently higher in every general election over the past decade in states with greater shares of overall ballots cast by mail. Drawing on turnout data from the 2012-2020 Current Population Survey (CPS) and the Cooperative Election Study (CES), authors find states with greater usage of mail voting experience higher overall voter turnout.

This research assesses whether messages reinforcing election integrity increased participation in the 2020 election through a large-scale voter mobilization field experiment in California. Registrants were mailed a letter that described either existing safeguards to prevent vote-by-mail fraud or the ability to track one’s ballot and ensure that it was counted. Analysis of state voter records reveals that neither message increased turnout over a simple election reminder or even no contact, even among subgroups where larger effects might be expected.
