The Impact of COVID-19, Election Policies, and Partisanship on Voter Participation in the 2020 U.S. Election

The COVID-19 pandemic had the potential to wreak havoc on elections. Democracies initiated varied policies to minimize health risks to voters and election workers. This study assesses the impact of voting policies, personal exposure to COVID, and partisanship on voter behavior in the 2020 U.S. general election. Using a comparative state-politics approach and new data, we demonstrate that exposure to COVID substantially influenced voter turnout, and election policies had a major effect on whether a voter cast a ballot by mail, early in-person, or in-person on Election Day. Unique circumstances, including the emergence of voting policies as a polarizing issue, also spawned a new partisan voting gap that is especially prominent among heavy news consumers. Compared to 2018, many more Democrats than Republicans abandoned Election Day voting in favor of mail voting.
