The survey included an expansive set of disability questions and validated voter turnout responses against state voter files. The analyses reveal a high disability incidence; large disability turnout gaps; and even greater gaps estimated with validated compared to reported turnout. Much smaller turnout gaps and better voting experiences are found in the states that conduct their elections with all-mail voting.

This research's findings suggest that signature validation, which serves as a primary safeguard for mail voting integrity, may be systematically influenced by underlying biases

Registered voters in some legislative districts in Los Angeles County were subjected to universal voting by mail in the March 2020 primary. This research indicate that voter turnout increased by 3 to 4 percentage points for voters who do not automatically receive a mail ballot, and the increase is generally larger for registered partisan voters than those without a party affiliation.

In this paper, authors use a national survey of poll workers from the 2022 midterm election to analyze whether there are systematic differences between experienced and inexperienced poll workers in how they manage polling sites. They finds that experienced poll workers are more likely to say that their training prepared them for the election, yet their experience also correlates with more conflicts involving poll watchers and voters. This research fills a crucial gap in understanding how poll workers' experience influences Election Day operations.

In this paper, authors draw upon the 2016 and 2020 Cooperative Election Study to analyze the likelihood that Trump supporters: (1) voted by mail, (2) self-reported voting by mail, and (3) self-reported not voting by mail when they did (misreporting VBM). In 2020, Trump supporters were markedly less likely to cast a VBM ballot and were also significantly more likely to disclaim voting by mail when they actually did.

This research finds evidence which implicates evaluator bias as the primary driver of racial disparities in vote by mail signature verification.

In this paper, authors invite the human factors and ergonomics community to engage with election administration research. The paper describes the complexity and scale of U.S. election administration and identifies open research challenges where human factors expertise is directly applicable, including accessible design, poll worker training, and error minimization.

This research analyzes the demographics of voters whose mail ballots are rejected in Washington and Colorado. It finds that younger voters and voters of color are more likely to have their ballots rejected due to a non-matching signature; however, almost half of these rejections are ultimately incorrect and are cured by the voter. Additional findings show that the experience of having a ballot rejected in one election, even if the issue is resolved through ballot curing, reduces the voter’s likelihood of participating in subsequent elections.

This research finds that when people vote by mail, they are more likely to successfully identify the candidates that are best aligned with their preferences.

In this paper, Carter takes an in-depth look at absentee/mail-in voting pre and post COVID-19 pandemic. The paper recommends that more states should expand their access to voting by passing no-excuse absentee/mail-in voting laws due to the positive impacts of expanded mail voting policies on voters during the pandemic.

In this MS thesis, Fry examines the accessibility of in-person voting equipment, specifically Ballot Marking Devices (BMDs) and Direct Recording Electronics (DREs), across U.S. elections from 2000 to 2024. She uses data from Verified Voting, the U.S. Census Bureau, and BMD/DRE manufacturers to analyze trends in the deployment of accessible equipment and to evaluate current systems against VVSG 2.0 Principle 7 (the right to vote privately and independently). The author finds that although accessible equipment coverage has improved substantially since HAVA, significant gaps remain in meeting current usability and accessibility standards.

The results indicate that state mail voting laws (universal mail voting or no-excuse absentee mail voting) and more widespread use of mail voting ballots can boost turnout in primary elections, particularly when combined with open or nonpartisan primary rules.
