You must have lived under a rock when you lived in Texas. Texas is a right to work state and no one has to be a member of a union to have a job.
During an election, if an election judge needs law enforcement help, such as a person or persons are violating the distance marker beyond which no one came come except a voter, the judge usually calls the constable who is elected to office in that precinct, and he deals with the problem. Either the people move behind the distance marker, or they go to jail. If the constable didn't do his job, he wouldn't be reelected to office.
Since this has come up in Texas, one can be sure our law enforcement will be ready to deal with the problem. They are Texans first and will arrest those outsiders if they come past those distance markers and won't move.
The only way to get into a polling place is to be a voter or an appointed poll watcher. Only two entities can appoint poll watchers - the county chairman of a party and a candidate can have one poll watcher in each voting precinct where the candidate is on the ballot. These watchers have a document showing they are appointed poll watchers and they must deliver their document to the election judge the moment they enter a polling place. The document is signed by the county chairman or the candidate who appointed the poll watcher. Every poll watcher has to be a resident of that county - no UN foreigner piece of crap can be a poll watcher as they live in some other country.
UN dummies either follow our laws or they are going to jail, period.
Under a rock?

Not hardly...
Anyone beholden to a Union is automatically suspect IMO. History bears this out rather well...
