Every citizen is expected to vote.
The lesson learned is that it is not okay to vote for a candidate just because he is a gifted public speaker.
"Neither did I think that a pleasant face and a gifted tongue were proof of a wise mind. Those who had given me such assurances about him must have been poor judges. They thought him wise and thoughtful simply because they were charmed by his manner of speech."
-St. Augustine (Confessiones, Book V).
