In simplest and most idealistic terms: The Senators speak for the needs and culture of their state. They make the functional apparatus of the republic.
Congress people of the house speak for their constituents and give us the representative democracy part. The courts speak for the law and maintain the "constitutional" part of our constitutional democratic republic. The POTUS should speak for the nation and serves and a check and balance against the others.
Were they monkey-fighting snakes on a Monday-Friday plane?
