This research finds that when automatic voter registration (AVR) is endorsed by Democratic leaders, Republicans (and independents) expect AVR to reduce the fairness and legitimacy of elections, while Democrats are generally resistant to partisan cues.

This research tests four explanations for how vote by mail voters choose to return their ballot, including the social rewards of voting, the costs of voting, trust in U.S. Postal Service and a preference to cast a ballot after campaigning ends. It finds supporting evidence for each explanation conditioned by prior history of voting.

The research finds that online voter registration systems in some states have vulnerabilities that allow adversaries to alter or effectively prevent a voter's registration. The analysis additionally finds that ballot tracking systems raise serious privacy questions surrounding ease of access to voter data.

In this article, using data from Orange County, California, the researchers develop two methods for evaluating the quality of voter registration data as it changes over time: (a) generating audit data by repeated record linkage across periodic snapshots of a given database and monitoring it for sudden anomalous changes and (b) identifying duplicates via an efficient, automated duplicate detection, and tracking new duplicates and deduplication efforts over time.

This study investigates the reliability of Florida’s voter registration files through a phone survey, asking respondents to verify their records. Authors find 17.7% of registrants fail to verify at least one identifying piece of information.

The research finds that drop boxes have a positive effect on voter turnout and that decreasing the distance to these boxes can lead to an increased likelihood of voting.

This research develops and applies a method to estimate how many people voted twice in the 2012 presidential election. It estimates that about one in 4,000 voters cast two ballots, although an audit suggests that the true rate may be lower due to small errors in electronic vote records.

This research argues that local challenges remain when maintaining voters’ registration and voting history information, which undermines the quality of voter lists and the integrity of the electoral process. It analyzes Mississippi’s Statewide Election Management System (SEMS) records and finds that voter registration and voting history errors are linked to the county’s active and inactive registered voter rates and demographic characteristics.

Authors collect data from 1996-2018 on all three U.S. states who implemented universal vote-by-mail in a staggered fashion across counties, allowing us to use a difference-in-differences design at the county level to estimate causal effects. They find that: (1) universal vote-by-mail does not appear to affect either party's share of turnout; (2) universal vote-by-mail does not appear to increase either party's vote share; and (3) universal vote-by-mail modestly increases overall average turnout rates, in line with previous estimates.

Since the passage of the Military and Overseas Voter Empowerment of 2009, many technology solutions have been developed to help UOCAVA voters request, receive and return their ballots. This report examines the preliminary and current landscape of these technology solutions and identifies barriers to ensuring their sustainability. The report also identifies areas of further research related to emerging UOCAVA balloting solutions.

This analysis focuses on whether counties that had previously been “covered” purged voters at a higher rate than noncovered counties after the coverage formula was struck down. It finds increases in purge rate of between 1.5 and 4.5 points in formerly covered jurisdictions post-Shelby, compared with counties that had not been subject to preclearance. Most of the increase came immediately, as the effect in 2014 is substantively and significantly higher than that in 2016.

Examining two states that have conducted a staggered rollout of mandatory vote-by-mail (Washington and Utah), this research finds that mandatory vote-by-mail slightly increases voter turnout but has no effect on election outcomes at various levels of government.
