Voting by Mail Reports

This report details how American voters experienced the 2024 general election. It is based on a survey of 10,200 registered voters, including 200 from each state plus D.C.

This research analyzes the demographics of voters whose mail ballots are rejected in Washington and Colorado. It finds that younger voters and voters of color are more likely to have their ballots rejected due to a non-matching signature; however, almost half of these rejections are ultimately incorrect and are cured by the voter. Additional findings show that the experience of having a ballot rejected in one election, even if the issue is resolved through ballot curing, reduces the voter’s likelihood of participating in subsequent elections.

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.

Voter Registration Reports

Over the last two decades, states have implemented several innovative policies that streamline the process of voter registration, promote voter list accuracy, and create more options for eligible citizens to register or update their voter registration. Such policy innovations include online voter registration, same-day voter registration, and automatic voter registration. The number of states that have implemented at least one of these three voter registration methods increased from seven states in 2000 to 46 states in 2024.
