I really like the vote by mail system in Pennsylvania. The primary ballot came promptly and included explanations, allowing me to do research alongside the descriptions and the candidates. There was a privacy envelope for its return, which went inside the envelope that included my name and address to ensure my name at my address would only be counted once. It included a reminder email and a *confirmation* email saying my ballot arrived successfully, and then it told me I could not vote in person during the primary.
Mailing the thing was free. :tada emoji:
The only change I’d make is have the circles to choose one’s candidates be larger to accommodate people with hand mobility issues.
