For starters, we need voter ID laws. Everyone eligible who wants to vote must be vetted for eligibility, residence, and acknowledge participating in any kind of voter or election fraud is a felony and a lifetime ban from ever voting again.
Basics: 18 or over, must be a citizen, no felonies, must still be alive.
One person, one vote.
Everyone must use a paper ballot submitted at the polling place on Election Day unless you will be out of the country and you request an absentee ballot in advance.
Elderly and sick people who are unable to leave their house can call a hotline for assistance.
What else?
And ballots must be retained for not less than 10 years in the event that the election results must be reevaluated for any reason.
Sounds like you've got it. We also need serious penalty for fraud and interference resulting in an exceptionally long sentence and never bring able to vote again. Now we just need a PDF we can print off and mail to those lazy fuckers we did not elect.
We could get rid of the machines and vote by cell phone.
Yes it can be secure with finger print ID, facial recognition or even a secret pin number just like your credit card or bank card.
The main thing is make it a 2 step process. Once voting is finished and recorded in a general ledger with numbered votes then a person checks how their vote has been recorded and makes it official by verifying their vote.
Your kidding right?
