Alien Abduction and Voter Impersonation in the 2012 U.S. General Election: Evidence from a Survey List Experiment

Abstract State legislatures around the United States have entertained—and passed—laws requiring voters to present various forms of state-issued identification in order to cast ballots. Proponents argue that such laws protect the integrity of the electoral process, sometimes claiming that fraudulent voting is widespread. We report the results of a survey list experiment fielded immediately after the 2012 U.S. general election designed to measure the prevalence of one specific type of voter fraud most relevant to voter ID laws: voter impersonation.
