In Russia, they have only 1 party left, so the party clearly doesn’t matter. In Usa, it is not an official dictator yet. In other countries with a dictatorship, I don’t know about their parties. So do you know any examples where the parties still matter?
NK is such an interesting case. They even have a party for North Korean Japanese voters. And with a 13% turnout across all the non-WPK parties, that’s a large amount of social influence they must wield relative to the WPK, even if they are under their control.
