The US Federal Constitution needs to be redefined at its core: The way the Federal Government is elected and the balance of powers between the branches and the different levels of Government, local, state, federal, needs to be actualized returning to, and improving the original design.
First the President should be elected by direct vote under uniform rules established and implemented by the Federal Government. One Citizen, one vote, under uniform federal rules.
Second the Senators should become State ambassadors before and in the Federal Government. One Senator per State, nominated by the State Governor and ratified by the State Legislature. Above the Federal Supreme Court there should be the Annual States Supreme Court Judges Conclave, to convene for 30 days, once a year.
Finally and foremost the Union must be redefined as a Voluntary Confederation of Sovereign Nation States, where each State has the right to have and protect its own national Identity to the extend of leaving the Union, using a predetermined process, if its own national identity is threaten.
To leave the Union the permanent residents of a State most vote for separation, in two consecutive referendums, two years apart, then a period of negotiation on the terms of separation will follow, and finally a final referendum where the permanent residents of the State will ratify their separation from the union. The Union has no right to impose sanctions on a departing state. Any use of military force against the departing state will be considered an act of aggression against an Independent, Sovereign Nation State.
