Should have a voice
I think this is a great idea and I would make only two changes. I don't think that there should be any non-voting members of the House, all delegates should have a vote.
And I think that every Amerindian tribe recognized by the U.S. government should have a member in the U.S. House.
You should only get Senators if you are a state, but all tribes and protectorates should have an active voice in Congress.
Identity in the tribe
““They want to be someone other than who they are. That’s the great irony of identity politics: They seek identity in the tribe because they are failed individuals. They are a chain composed exclusively of weak links. What they are engaged in isn’t politics, but theater: play-acting in the hopes of achieving catharsis.””
