I'm an outsider; is the US a democratic union of 50 states (plus districts and territories) or is it a democratic union of ~ 335 million individuals?

Is the EU vote in Brussels passed by countries or by individual citizens?

As I recall the current electoral system was set up to weight the votes of states that were members of the union .. if the US has moved to a single unified country of individuals then it might be time to reset the rules (the US founders would be in favour if I read their comments on evolving systems correctly).

Perhaps 'dated' is a better description than 'broken'.
