The research finds that counties that moved to send registered voters mail-in ballots ahead of Election Day experienced 2.6 percent higher turnout compared to counties that made no change, although lesser reforms may have hindered turnout. Additionally no evidence is found that making voting by mail easier conferred a partisan advantage.

This brief studies trends in mail ballot rejection rates in 2020 compared to previous years and how different factors, including sets of policies and policy changes, the political environment, and voter outreach, may have contributed to these changes in an extraordinary election year. Authors note potential areas of further study to better understand how voters casting their ballots by mail can ensure their votes are counted.
Using surveys of registered voters conducted in April and May 2020 designed to assess the support for various electoral reforms, the research shows that the overall support for expanding VBM in April 2020 falls sharply after just six weeks because Republicans became less worried about catching COVID-19, and unconcerned Republicans became far more opposed to VBM. These differences not only persisted, but actually increased even further between May and Election Day according to a survey done using a different methodology in November 2020.
This brief provides recommendations for the U.S. Department of Justice Election Threats Task Force aimed at strengthening protections for election workers against threats of violence. Recommendations include issuing additional guidance for law enforcement, noting the limitations of federal laws protecting election officials and addressing them as well as identifying alternatives to criminal prosecution to help deter threats and esnure the safety of election workers.
While the evidence is clear that 2020 voters shifted away from Election Day voting in favor of vote-by-mail and early voting, very is known about how health risk versus party polarization around risk assessment influenced how and when to vote. The research finds that age and party were large factors in vote mode decisions in 2020, but not in 2016 or 2018.
Drawing on a large survey of validated Florida voters, including those who regularly vote by mail, the research finds that retrospective and prospective misreporting of vote method prior to the 2020 General Election was driven primarily by support for Trump. The president’s supporters who were most politically aware were most likely to disavow their own voting by mail and misreport their anticipated vote method in the November election.
This analysis of the Florida general elections of 2016, 2018, and 2020 shows that voters inexperienced with mail voting disproportionately submit ballots that end up rejected due to (1) late arrival at elections offices or (2) signature defects on return envelopes. Inexperienced mail voters are up to three times more likely to have their ballots rejected compared to experienced mail voters.
The 2021 Local Election Official Survey explored the views and opinions of 233 local election officials. The survey finds that most election officials are motivated by desires to serve their local community, are concerned about harassment while on the job, and believe that social media is increasing political division.
All mail voting in Colorado had a positive overall turnout effect of approximately 8 percentage points—translating into an additional 900,000 ballots being cast between 2014 and 2018.
In this paper, Jones and Stein test an expanded explanation for poll worker recruitment focused on reducing the demand for poll workers through efficiency gains. Based on the results of a national panel survey of election officials, authors find that in-person precinct voting on Election Day is a significant source of difficulty in obtaining poll workers. They offer widely available and political neutral strategies aimed at reducing poll worker scarcity.
With Maine as a case study, the research shows that, in the past four general elections, over 10% of vote-by-mail ballots arrived at local elections offices either on Election Day itself or one day earlier. Moreover, of the vote-by-mail ballots most vulnerable to postal delivery disruptions, a greater share of them were cast by unaffiliated voters and Democrats than by Republicans.
