That and a couple of dollars might get you a cup of coffee at some gas station.
Can voting get hacked, absolutely they can and probably have been. Every computer device can be hacked, we still use them in every aspect of our lives.
I can give 4 areas in the election that need to be addressed before voting machines.
Universal Voter ID.
Universal Mail In Balloting
Ballot Harvesting
Fraudulent or dirty voter rolls.
If 10,000 fraudulent ballots come in late at night, you could eliminate all voting machines and vote outcome would be the same.
The point is to stop fraudulent ballots from happening at the beginning, before they get accepted as official votes, at that time it’s too late regardless of the counting method.
Somehow Western Europe makes do with hand counted paper ballots, yet we are unable to. Odd.
