@libertybele@mystery-ak @CatherineofAragon The number of voters per voting precinct will change when the county does redistricting after a US census. There is a number of citizens allowed in a voting precinct, above which number a voting precinct must redistrict to stay under, or at, the legal number.
About more voters voting than registered:
If a person shows up at a voting precinct and is not on the voter list of that precinct, the clerk will check their address and if the person is another voter precinct, the person is told to go to that precinct to vote. The person can say he/she wants to vote there, and he/she is given a Provisional Paper Ballot - not allowed to vote on a machine if the county uses that method. This person will show up in the number of those who voted in that precinct,
which would account for more people voting there than registered. However, that paper ballot is not yet counted. It goes to the Early Voting Ballot Board, of which I was a Judge for ten years. On the day after voting day, that board meets and goes over the Provisional Ballots to see if any of them should be counted. In ten years, we never found a legal voter in a precinct who voted a Provisional Ballot - they were all rejected.
Paper ballots are also used to mail to those voting by mail. Those ballots also go to the Early Voting Ballot Board to be processed. A number of people make mistakes on the legal paperwork and their mail ballot has to be rejected. It was my job to send letters to those whose ballots were rejected, both the mail ones and the Provisional Ballot ones. My name had to be on the letter as the Judge. It was better for me to be somewhere else than home, on the day I knew they got the letter.
I did get phone calls from some of the people whose ballot was rejected, but I had the record of why each one was rejected and that was also in the letter, so I explained that to the voter again and told him/her what to do so their next ballot would not be rejected. I never had irate voters call me.
