Each county in the country has their own voter list with backups and printed copies. If one wants the names, addresses, etcs., one can buy it from the county. It is not a secret. I had numerous county voter lists on my computer when I worked for the Republican Party. I did not have to buy them, but in earlier years before I worked for the state party, I did have to buy our county list which was on a disk. On election day, a polling place has a print out of that list to check the voter in. So, each county has their own list they maintain.
The Secretary of State in each state has a voter list of all in the state. If the Russians got into that list, it would not affect a county list.
When I first read about this, it sounded like, and still does, the Russians wanted to, or did, send emails to people. If they had a county voter list, which anyone can buy on a disk, they could send letters or emails, if the email was listed.
I was still working for the party, when it became possible for the Republican National Committee, to have a voter list of all registered voters in the country. The Russians could hack into that list, but that would not affect a county voter list. Remember, every election is held in a county or parish. They have the control of that election in their county. Consider where you vote - you vote in your county at your voter precinct. You vote on a machine that is not connected to the internet. It is a dumb machine that counts. Some of you may be in a small county that votes by paper ballots - that is legal.
When you read about "Oh, my God, the Russians broke into voting machines!", remember your county has their own voter list with backups and their voting machines are locked in a room and not plugged into anything, they just sit there until election day. Your county runs your election and remember the process you went through at your voting precinct. At the end of election day, your county has a central counting station where all the votes from each precinct goes. The votes are counted there by human beings assigned to work there. The totals are reported to the Secretary of State.
If you live in Texas, I wrote the law that central counting stations in every county in Texas must follow regarding who can be in there and count your vote.
