This report explores the legibility and readability of summary ballots printed by ballot marking devices and the ability of optical character recognition (OCR) applications commonly to voice (read) summary ballots. The report identifies typographic elements that might make it easier to read a ballot visually, the feasibility of using OCR to allow blind or low vision voters to hear their ballot read accurately, and whether there is a relationship between the design elements that support both visual and OCR-assisted reading.

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. Key findings from mail voting include: mail voting decreased to 29% from 43% in 2020; 37% of Democrats used mail voting compared to 24% for Republicans; few voters reported issue with requesting or completing a mail ballot; 3% of voters who returned their ballot via mail encountered disruptions.

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.

Voting by Mail Issue Briefs

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.

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.
