These systems have no other purpose but cheating.
The Canadians have a manual paper system with multi-party guarded counts. It scales, it works, it can be recounted.
E-voting was an idea slammed home in every case. It cannot be secured. No purpose but an invisible and unstoppable means to alter vote counts. The counts have been altered, the machines and systems compromised numerous times on investigation. And that's just outside cracking; anyone on the inside can change code, accumulated totals, and elections at will, if they aren't stupid enough to get greedy. Recounts recount altered votes, so they are useless. We can't analyze code; it can change on the fly. We can't look at the data, because all wee see is the altered datasets.
We need to shut these cheating boxes down and switch to paper before we can't actually cast a meaningful vote ever again.
