This report provides practical guidance for conducting tabulation audits, with discussion of audit methods and links to risk limiting audit resources.

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 report outlines Virginia's 2022 risk limiting audit process, results, observations, and recommendations for future audits.

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

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

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.

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

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.
