That’s a good point. But we shouldn’t even have “polling stations” manned by humans. We should tie in voting with the submission of 1040 tax forms. Don’t need to pay tax? Still submit the form. Everyone should be declaring what they owe or don’t owe. And we should have tax submissions 100 electronic and without the need for CPAs, no matter what kind of assets and debts you carry.
Sadly voting is inefficient and poorly designed by way of legislation. There is no technical reason voting cannot be done via smart phone or other convenient method.
