To me, the problem is not electronic voting machines themselves, but rather the fact that they can be programmed to produce whatever results the programmers, or the company they work for, desires.
Electronic voting machines
could greatly simplify and streamline the voting process, but the ones that exist now are so easily subject to fraud that they should be trashed and banned.
In my view, it would be a good idea to have a tax-supported governmental agency, a voting-systems commission where technical experts of all political persuasions designed both the hardware and software of an electronic voting machine/system. Both the hardware and software would be subject to public and private scrutiny by anyone at any time, by any concerned citizens group or group of non-partisan programmers. The software would be non-proprietary and the source code of the programs would be able to be obtained by anyone or any group. The administration and oversight would, mandated by law, be composed of a diverse selection of people from both or all major political parties.
This tax-funded project for the American people would be a non-partisan undertaking to produce voting machines that would then be uniform throughout the country and upon which each individual could rely and feel confident in the election and voting process.
That is an ideal. We are far from that ideal with proprietary voting machines bought by the government from private (and often partisan) companies with secret proprietary software. What we have now truly is "black box" voting, and in my view, it must go--
