Here is a plan where this is happening:
Contact your SOS office and tell them that this is happening. Go in a huge mob and confront whomever that person is.
Stand outside of the polling place (at the required distance) with a huge sign citing what is happening, and stop everyone going in and alert them that the polling machines there are doing this, and to watch what you are doing.
If you know this is happening where you live, and aren’t doing anything, then you are just as much part of the fraud as the machine.
Sounds like a recipe for disaster to me.
