How about using something like an ID card with attached chip that can be used to digitally sign things? Works great in Belgium.
I get it, most people aren't always rational about these things.
The sentiment goes something like this:
- Conservatives gave up on minorities, historically stated that the less they vote, the better - Conservatives push the narrative that voting fraud is a big problem, and that the liberals are doing it (many high profile member's of Trump's family/cabinet are registered to vote in many states simultaneously)
- They push for Voter ID laws and push back against weekend voting days, as it makes it harder for hourly/poor/minority voters to show up and vote.
So it would probably be a great idea, but since conservatives consider non-white franchising is an existential threat to their cause, they'll probably scream "state's rights" and block it from happening.
