The educational article on the Constitution by Professor Natelson was ausgezeichnet (excellent). I hope The Epoch Times reprints it once a year or publishes it in a small booklet attached to a pocket Constitution.
As I read the Constitution, the Senate represents the states through their senators. Every state has one state government and that is what the senators and the senate represent, not the people of the states (The House represents them). He also mentioned specific tasks assigned to the Senate. In addition, the Senate has two broader functions: He mentioned one, to moderate volatility and prevent hasty mistakes from the House. The second is to enforce the tenth amendment as only the Senate can.
