People in rural areas whose polling station closed thanks to Republicans, and who can’t drive 30 miles to the next one wanted to use the mail-in ballots. And Democrats were very happy to allow it. But then Republicans pointed out all the ways the mailing system and ballot harvesting was very unreliable. And both sides have a point. Taken to the extreme, both disenfranchisement and physical mail suck for voting.
In contrast, people could have an option to vote from their computer and use their phone to scan the QR code and confirm their vote and sign it. They can then verify their vote was included correctly!
I have explained at length how crypto would make it a lot more verifiable and reliable.
Everyone would be able to check:
1) their own vote was counted in their district
2) their own district was counted in the total
3) the number of votes and turnout in each district, matching the number of signed checkins
4) mutually distrusting parties in each district saw each ballot being cast (or a random sample) and were satisfied that the electronic record matches whatever receipt was generated
None of these can be directly verified by nearly anyone participating in a paper election.
