The states, individually, are sovereign entities, headed by governors elected by the people of their respective states
thanks to the creation of the EU, I’ve modified my paradigm on this to a more “pre-civil war” perspective. I live in a country called Kentucky. It is a sovereign country with the exception of what it gives up in sovereignity to the overlying constitution of the union of countries of which it is a member. The US is like the EU and Kentucky and California are like France and Germany.
