Question

why can't the communist have free and fair elections

Answer 1

communist have elections we can be free and fair, there maybe no violence involved but the problem is that that the contestants are from a single party and so are of the same ideas and believes for a countries, so they can be free and fair but not democratic and that is they can't be free and fair absolutely

Answer 2

Let me take example of china to explain the answer. In China, only the communist party is allowed to rule. Although legally ,people are free to form political parties , it does not happen because the electoral system does not permit free competition for power. We cannot consider this system a good option because this Is not a democratic option. Any democratic system must allow at least two parties to compete in elections and provide a fair chance for competing parties to come to power.
