Easy fix.

Use technology that is easy enough for those that run the ballots to completely understand the system and to fully understand the implications. We know what properties an election should have. Somehow, no electronic system on the market today can fulfill them all. So the obvious solution is to stick with paper systems and have humans tally the results.

Sometimes, it is simply more important to have a system you can trust, that will work properly and can easily be audited, than to have the very latest in technology. Even cost is no argument: A system that looks costly to run but will reliably do so uneventfully, might suddenly look a lot cheaper than the fancy replacements full of projected savings bullshit that then cause endless squabbles, disputes, and dissatisfaction.
