The good news is that many of the barriers that voters with disabilities face are easy to solve. Registering to vote can be made easier by ensuring the accessibility of online registration forms and allowing same-day voter registration.
Many polling location accessibility issues, such as ensuring accessible pathways have proper signage and that ballot-marking devices are properly setup, can be addressed by making sure poll workers have adequate training.
Many of these accommodations can be made with minimal, or even no costs. Not only would these measures greatly improve access to the ballot for voters with disabilities, but it would also improve access for other marginalized communities who are also disenfranchised by these same barriers.
