There is a difference between poll workers and poll watchers. Workers likely need to be Fulton Co. residents. (at least in WV they need to be residents of the county they work in). They process the voters that show up on election day. Poll watchers are partisan people who watch the process and have a (limited) ability to challenge voters and votes. They are generally regarded as a nuisance by the workers trying to run a fair election and as the enemy of those trying to cheat. They need video and audio evidence. Most places recording devices in election venues are illegal. Do not know if they need to be GA residents.
Well thank goodness the ACLU poll workers got rid of those pesky GOP poll watchers and the press at State Farm arena on election night so they could scan over 100k votes for Biden without any observation....
