“First, divide the nation into 50 Districts, each District into 50 Regions, each Region into 50 Wards, and each Ward into 50 Precincts. There will be 50 Districts, 2,500 Regions, 125,000 Wards and 6.25 Million Precincts. If you had 312.5 million people voting—about the population of the United States–then there would be 50 voters in each Precinct.”
