It’s an interesting notion, but I think it would be an unwieldy mess. Reapportionment would be a nightmare, and you’d have a huge number of rotten borough districts in urban areas and certain sections of the country. Imagine the city of Los Angeles alone with 76 Congressmembers, virtually all of whom would be either Maxine Waters or radical La Raza types.
76 out of over 6000 representatives is less than 2% of the total number of reps. Fact is that just one state needed to ratify it in 1790 but it was tabled. The spirit of that apportionment was held to until our government decided to freeze it at 435 by statute.
Forget the difficulties in implementation, this is a perfectly legal method to revolt against the Feds from the local level. Just need a high profile lawmaker to take up the banner.
