State vote by mail policies have been expanded to facilitate voting by people with disabilities, but rely on voter signatures to verify an individual's identity. This report examines how signatures and signature comparison are used in elections, explores the uses and types of signatures in other contexts, and discusses alternatives being developed that could be used in elections.

This white paper reviews literature related to trust in elections.
This National Task Force on Election Crises resource explains how election officials communicate results, conduct canvasses and audits, and confirm outcomes to build public trust.
In this paper, authors examine the impact of same day registration (SDR) policies on younger voters. They find that SDR disproportionately increases turnout among individuals aged 18–24 and is especially pronounced in presidential elections. The effects of early voting and other reforms are smaller and do not consistently vary by age.
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.
This research finds that explicit cues about rigged voting machines increase belief in such theories, especially when the cues target the opposing political party. Explicit cues also decrease confidence in elections regardless of the targeted party, but they have no effect on satisfaction with democracy or support for election security funding.
This report examines barriers that prevent voters with disabilities from voting privately and independently. The report recommends several actions to overcome these barriers, including improving the accessibility of voting information and access to accessible voting technology, and integrating the disability community into all aspects of voting, among other things.
This post-election survey reports on how Americans cast ballots in 2022 and how confident they were that votes were counted accurately.
This research assesses whether messages reinforcing election integrity increased participation in the 2020 election through a large-scale voter mobilization field experiment. California registrants were mailed a letter that described either existing safeguards to prevent vote-by-mail fraud or the ability to track one’s ballot and ensure that it was counted. Analysis of state voter records reveals that neither message increased turnout over a simple election reminder or even no contact.
This report summarizes the findings of a 2022 national survey of eligible voters with and without disabilities to understand the role of the internet in accessing voting information. Topics covered include computer and internet use, sources of information on the voting process used in 2020, and accessibility of information sources, among other topics.
Authors examine the effects of state election administration laws on voter turnout at the state and individual levels for people with disabilities and compare them to that of the non-disabled population. They find that convenience voting reforms such as same-day registration and election-day registration boost turnout for both populations while all mail elections decrease the turnout gap between people with disabilities and the non-disabled.
This report highlights key trends in voter turnout among voters with disabilities in the 2022 elections. Authors note an increase in turnout among these voters compared to the 2018 midterms, especially in states with expanded vote by mail policies. However, approx. 14% of voters with disabilities reported some difficulties voting.
