I could have voted another ballot. In my county it says on the back of the ballot you can take the mail-in ballot in, surrender it, and get a new ballot. I just used the mail in one though.
I just thought it might lead to some interesting questions for anons to ask when they go in to vote in some of the upcoming elections in other parts of the country.
The online info does not need to identify the voter. It could be indexed by ballot number.
If anyone could look up all ballots cast and how they were tallied then the system would be fully audit-able.
But I do agree such a listing should not show voter identifying information.
