Exactly. The problems in the US run way deeper than just the technicalities of voting. Both sides have been trying to bend the processes and rules their way for decades. Gerrymandering, campaign financing, elaborate propaganda campaigns, special interest lobbying (including by companies making voting machines), foreign interference (e.g. https://www.themoscowtimes.com/2022/11/07/putin-linked-busin...), etc.

There is no basis for trust here that parties are even trying to play by the rules. They are actively using every trick known to them to gain an advantage and the financial stakes are high enough for people to look the other way given enough plausible deniability.

So, start with making the voting process as transparent as possible and just go back to counting votes manually. It won't solve all the issues but it will reduce the endless bickering about who actually won the votes that were issued.
