So yeah, what if each State in the USA had the same relationships with each other as the Princely States in the Holy Roman Empire? Each State would provide a candidate for Presidency after each term and people would not only be voting for the person, but the State in which the capital of the USA would be? Would there even be a need for Washington D.C. as a State? What States would be the Austria and Bohemia of the HRE that seem to dominate the others? Would the USA even be able to last to the modern day and would the Civil-War in this timeline just be a breakaway alliance?
