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?
Just take a look at the countries that have the word “democratic” in their name. Seems like that’s the unofficial way to let everyone know exactly how authoritarian the country actually is.
