So, we live in a Republic. Democracy is like the Ancient Greeks had. They voted themselves into oblivion....
Bernie, specifically, is a Socialist, not for Democracy unless the people's votes can be used to obtain Socialist/Communist goals. There are no voices of dissent in Communist countries, because the state runs all media. If there is a dissenter, it's because they are allowed to be, by the state, for state purposes. All Communist states become dictatorships and/or broken up by their relatives in other nations. That's just actual history.
