Those who are disabled, such as the blind, usually vote at a polling place at an accessible voting machine. However, if the visually-impaired received a mail-in ballot, they would still need assistance to fill it out. That would make it impossible to keep their votes private. West Virginia has another alternative for their June 9th primary. Online voting.
“If somebody has a better approach to fully enfranchise 30 million disabled voters we’re open to it.” – Bryan Finney, founder, and CEO of Democracy Live
West Virginia has allowed eligible overseas and military voters to cast ballots through a mobile app since 2018. They have expanded their technology to include a cloud portal for the aforementioned voters plus those residents with disabilities.
