Because free and fair elections are determined internally as they always have? Whether elections are free and fair is determined by the state.
America cannot make Cuban elections less free or fair and you would have to fundamentally not understand what “free and fair” elections are to assert otherwise. If Cuban elections are neither free nor fair the culprit would be the Cuban government/Cuban Communist Party.
Cuba seems to only prmit the Cuban Communist Party to exist as a party. Robbing the citizenry the choice of what political path to follow is not the actions of free elections but is oppressive. Why would someone back the oppression of the will of the people?

The Gelph-Ghibelline conflict was about secular monarchism vs religious authority. Im not sure I see the point you’re making.
