I’m a Minnesota election judge (poll worker). In rural areas voter fraud is minimal, since we know most of the people who walk in to vote. Our local County Auditor is the head election official and is competent and honest.
Voter fraud in the local precinct polling place is much more likely in urban areas where people are somewhat anonymous. Without voter ID there is little to prevent someone from using another person’s name.
Urban areas have county government that is predominately Democrat. The polling places count ballots. The actual votes for political office are tallied at the county level. That makes wholesale fraud possible and allows political operatives in elected offices to manufacture votes. When urban precincts (with the most up-to-date technology) are slow to report results it is a sign of vote fraud by the elected officials who are in charge of vote counts.
No wonder those who live in the burbs or have there vote canceled out.
