What we need to do is make the vote public that way no cheating can occur.  It would be a realitively simple process to have an excel file with people names and who they voted for so they can check to make sure the vote was talloed right and if that isnt who they voted for they can demand answers.  



If you really want some secrecy you could attach numbers to peoples ballots and use those numbers instead of a name for the file.

I like the way Seattle / King County does it, actually.

Your ballot has a unique ID on the bottom, and comes with a QR code for you to track your ballot's progress. You can see when your ballot has been received by the voting office, when its outer signature has been verified  and every other step including when your vote has been counted.

Also, every step of the process is livestreamed and thrown up on a government website. I've spent my fair share of time watching government workers count ballots and make sure they didn't forget a basket somewhere.

This process allows every voter to make sure their vote was counted properly, without having to disclose who voted for who.
