This research finds that voters with greater general political knowledge are more likely to vote early, and those with low political knowledge are more likely to wait until Election Day to cast their ballot.

The research finds that information about possible coronavirus exposures decreases comfort with voting in-person yet does not increase comfort with voting by mail.

This report seeks to inform discourse surrounding the implementation and impacts of vote by mail (VBM) policies by evaluating modern use-cases. Authors examine the history of VBM policies, the landscape of current research on VBM and analyze the use of VBM in Utah as a caste study. Report findings indicate that, when implemented well, VBM is a secure and successful means of casting a ballot

This report describes the Carter Center's observation of the 2022 risk limiting audit conducted in Georgia.

Authors use official statewide voter file and mail-in ballot data from the 2018 midterm election in Georgia to test whether certain voters are more likely to cast a mail ballot that does not count. In their analysis, authors distinguish between ballots rejected for lateness and those rejected for a mistake on the return envelope, finding that newly registered, young, and minority voters have higher rejection rates compared with their counterparts.

These results suggest that making it easier to vote by mail—especially mailing every voter a ballot—generally does increase turnout, both before and during the 2020 election. By contrast, the same policies do not have robust partisan effects, and in many models, they tilt the results in a more Republican direction.

This report, issued by the Office of the State Auditor, summarizes a statistical analysis of ballots submitted in the Washington 2020 general elections, with an emphasis on understanding common reasons and predictors of ballot rejection. Its findings point to the county where a ballot was cast as being the most significant variable related to ballot rejection. The report concludes with recommendations for the state aimed at reducing ballot rejections.

Explains risk limiting audits (RLA) for observers, including steps, what observers should monitor, and how RLAs compare with other post-election checks.

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.

In this paper, authors present ALPHA, a flexible risk limiting audit method that can handle sampling without replacement and stratification while learning from audited ballots.
