CAP with a bunch of state studies. Here is the description for the series:

The integrity of elections in the United States demands that every eligible American is able to cast a ballot and trust that it will be counted. Americans have the right to choose their representatives and take part in electoral decision-making. But across the country, thousands of voters have not had their voices heard—either because of targeted voter suppression laws or poor election administration decisions.9 While the vast majority of Americans will vote without encountering difficulties, in recent election cycles, voters have faced preventable problems and unnecessary hurdles. Failures at the polls may deny individuals their right to participate in the democratic process.

This series of issue briefs assesses potential problems for voters in states that have experienced issues with election administration or recent changes to voting rules. Each brief analyzes steps to improve election performance and the voting experience. Ongoing lawsuits have led to significant changes in recent weeks, as federal judges have ruled that many provisions of new voting laws discriminate against voters of color and collectively burden voting rights for hundreds of thousands of Americans.10 Understanding the potential burdens that voters may face is a first step toward ensuring that voting is free, fair, and accessible for all Americans.
