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 post-election survey reports on how Americans cast ballots in 2022 and how confident they were that votes were counted accurately.

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.

This survey / research report focuses on election misinformation, fraud narratives, or public misperceptions and their effects on confidence in U.S. elections. It is relevant because beliefs about fraud and exposure to misleading claims are central mechanisms through which confidence in election outcomes rises or falls. For this dataset, it adds evidence on one of the recurring drivers of election trust: experience, information, partisanship, security, or institutional performance.

In researching how to ensure a statewide voter registration database’s accuracy and integrity, this analysis develops a Bayesian multivariate multilevel model to account for correlated patterns of change over time in multiple response variables, and label statewide anomalies using deviations from model predictions.

This research focuses on how the timing of voter file snapshots affects the most commonly cited advantage of voter file data: accurate measures of who votes.

The results in this article suggest that while convenience measures are designed to improve registration and voting rates, they may not result in across-the-board increases that some policymakers and advocates hope for. Nevertheless, there may be some differential impacts of these innovations on registration and turnout, particularly for youth and minority voters.

Using monthly data from the Colorado Department of Motor Vehicles from 2017 to 2021, the research studies a series of reforms to the voter registration process conducted by the DMV between 2018 and 2020. Prior to the reforms, a large majority of unregistered DMV patrons declined the opportunity to register when conducting a transaction. When voter registration became the clear default option for certain unregistered Colorado DMV patrons in 2020, very few of them subsequently opted out, which resulted in a sudden, large increase in the rate at which DMV patrons registered to vote.

This research uses difference-in-differences estimates that suggest that same day voter registration disproportionately increases turnout among individuals aged 18–24 (an effect between 3.1 and 7.3 percentage points).

This research finds that voters with greater general political knowledge are more likely to vote early, and those with low political knowledge are more likely to wait until Election Day to cast their ballot.

While the evidence is clear that 2020 voters shifted away from Election Day voting in favor of vote-by-mail and early voting, very is known about how health risk versus party polarization around risk assessment influenced how and when to vote. The research finds that age and party were large factors in vote mode decisions in 2020, but not in 2016 or 2018.
