While rejected mail ballots could over- or underestimate lost votes, a case study of Pennsylvania’s 2022 general election reveals at least 47% more lost votes than rejected mail ballots.

The analysis implies election workers are more likely to wrongly reject valid ballots for purported signature mismatch than to correctly reject invalidly signed returns. On the other hand, research on election workers as problem-solvers suggests they may try to minimize the wrongful rejection of ballots.

In this paper, authors examine ballot tracking use, local election official communication related to
ballot tracking options, how ballot tracking impacts ballot rejection, and the impact of ballot
tracking on voters’ information levels and attitudes about election integrity.

Even before the 2020 election, this reseach finds that voter turnout across the states is consistently higher in every general election over the past decade in states with greater shares of overall ballots cast by mail. Drawing on turnout data from the 2012-2020 Current Population Survey (CPS) and the Cooperative Election Study (CES), authors find states with greater usage of mail voting experience higher overall voter turnout.

In this paper, authors examine how decisions made by the USPS in the latter part of the nineteenth and early twentieth centuries have resulted in deeply entrenched structural inequities in the access to mail services on the Navajo Nation in Arizona when compared to rural nonreservation communities. These findings bear significant implications for mail ballot access by those of the Navajo Nation.

Using a comparative state-politics approach and new data, authors demonstrate that exposure to COVID substantially influenced voter turnout, and election policies had a major effect on whether a voter cast a ballot by mail, early in-person, or in-person on Election Day. Unique circumstances, including the emergence of voting policies as a polarizing issue, also spawned a new partisan voting gap that is especially prominent among heavy news consumers. Compared to 2018, many more Democrats than Republicans abandoned Election Day voting in favor of mail voting.

The findings of this research suggest that signature validation, which serves as a primary safeguard for mail voting integrity, may be systematically influenced by underlying biases.

This research assesses whether messages reinforcing election integrity increased participation in the 2020 election through a large-scale voter mobilization field experiment in 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, even among subgroups where larger effects might be expected.

In the 2020 North Carolina general election, about 82 percent of the roughly 26,000 voters who submitted mail ballots eligible for a cure process ultimately cast a counted ballot. About 39 percent of these counted ballots were cured in-person, and greater access to in-person curing options increased the likelihood that a ballot was cured. Democratic and non-major party registrants cured their ballots more often than Republican registrants, particularly when they lived in a county in which the Democratic Party was running a coordinated campaign focused on curing. While election officials sometimes attempted to inform voters by phone about the need to cure, there was no clear relationship between having a phone number recorded in a registration record and the likelihood that a ballot was cured.

Overall, 1.5 percent of all primary ballots cast and 1.1 percent of general election ballots cast were rejected across elections from 2012 to 2022 in Washington. There is evidence that voters of color have higher ballot rejection rates than White voters. Self-identifying male voters have slightly higher ballot rejection rates than self-identifying female voters in both primary and general elections. Younger voters have a much higher ballot rejection rate than older voters.

This study demonstrates that the level of accessibility of state absentee and mail voting laws as well as their administration have significant effects on voter turnout. The results also reveal that higher performing U.S. Postal Service administration can enhance the impact of absentee and mail voting laws, particularly in states with the most restrictive mail voting laws.

This report examines the impact of voting laws on voter turnout and choice of voting method (referred to from here on as voting method) in the 2020 election and the effects of in-person voting on the spread of COVID-19.
