evidence: Poll watchers cannot go into the area where voters are actually casting their ballots, and should rarely come into contact with voters. According to Department of State guidance, poll watchers must report any potential problems to the election judge on-site at polling locations, who will then determine if the poll watcher’s claims are reasonable and merit follow-through. [...] State guidance on what poll watchers can do outside polling locations is less clear. There are some hard rules. For example, it’s a federal offense to block access to polling locations. [...] For example, state guidance prohibits watchers from electioneering — campaigning in favor of a particular campaign or party — if they’re within 10 feet of the polling place or inside it.
