In English please?
Say I am a registered voter here in MN. There are a number of people that came with me on a bus that are not registered in MN because they are say illegals or are from WI.
By law I can go to the poll watcher and say hello my name is MNlurker and these people are legit.
If they were by themselves they would have to have proof of residence. With me there I AM their proof or residence.
