The research finds no evidence that voting by mail increases the risk of voter fraud overall. Between 2016 and 2019, RBM (VBM) states reported similar fraud rates to non-RBM (non-VBM) states. Moreover, it is estimated Washington would have reported 73 more cases of fraud between 2011 and 2019 had it not introduced its VBM law.

Using individual-level voter data from a 2020 Washington State election, the research shows that voters are more likely to use the nearest drop box to their residence relative to other drop boxes. In Washington’s 2020 August primary, 52% of drop box voters in our data used their nearest drop box.
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.
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.
This analysis shows that the implementation of vote by mail causes a significant decrease in voter confidence in Washington and Colorado. However, this decrease appears to be temporary, disappearing after only a single election cycle.
This paper provides a history of military voting by absentee ballot.
This United States Postal Service (USPS) report outlines the scope of election mail handled by USPS and identifies key service challenges including poorly designed ballot envelopes, tight state deadlines that don't align with postal delivery windows, and inconsistent postmarking requirements. The report identifies the "extraordinary measures" taken by USPS during election periods to effectively process and deliver election mail.
This MS thesis examines how polling place layout and path directionality affect voting system performance across turnout levels. The author models a two-step voting system in a theoretical 1,000 sq ft polling place using discrete event simulation, testing multiple layout configurations and voter routing strategies. They find that perimeter layouts with unidirectional voter flow minimize average travel distance and time-in-system across turnout levels.
In this paper, Pettigrew demonstrate that for every additional hour a voter waits in line, their probability of voting in the subsequent election drops by one percentage point. He finds that negative experiences carry over to future elections disproportionately for underrepresented voters.
In this paper, authors explore how ballot length affects specific types of voting errors, including human-machine interaction errors and voter ballot-marking errors.
In this paper, authors analyze how transitioning to vote centers impacts voters' experiences, noting that inadequate implementation may result in longer waits and increased voter dissatisfaction.
This paper explores how voting experiences and fraud perceptions influence voter confidence, revealing that negative voting experiences, particularly long wait times, are linked to decreased confidence and increased perceptions of fraud.
