Modern day society would be the one to judge how good or bad a politician was because the moment that a politician's reputation was ruined, that would be the end of their political career. The end result of overly seeking to represent the needs of "the people" would be a loss of self will, and in the great majority of situations, the majority opinion wasn't actually necessarily the truth or the best course of action, but rather just the one which appeared to be the best to everyone.
Because of this, any politician who was supported by the masses would actually themselves be controlled by the will of the masses. Even the most skilled politician who had been in power for a long period of time would only be someone who was more skilled at riding the flow. What accomplishments such a politician could achieve wouldn't be dependent on the individual's personal abilities, but rather how beloved they were by the God of Fate.
