If you have ever worked at a polling place, you know that we sign loyalty pledges. We sign something that says there's no ballot in that box before we close it and seal it. All the poll workers have to sign off on the material to say that everything was up and up, and there was no lost ballots. You have to account for every ballot that was given to you at a polling place, even the ones that are damaged. So you're given so many ballots. At the end you're going to say, I have this many voting ballots, this one unused, this one damaged. It has to come out equal. Otherwise you might be losing ballots.
