Election in Republic of Idiot

Once upon a time, there was a country named Republic of Idiot. Even though there were many intelligent people lived in that country but it was managed by a idiot, so the country never developed and poor.

There was a traditional activity in this country; every 5 years, people did vote for a new King to manage the country for next 5 years. Didn’t know since when, people were used to vote for a new King from a same family by generations to generations.

Was the King doing good job and managing well the country? The answered was a NO and fortunately all the kings from that family were IDIOT. However, due to unknown reason, even though those intelligent people kept complaining how bad those Kings were, they continued to vote for a King from the same family again and again every 5 years.

In such case, the same story kept repeating and repeating again in this country. People kept complaining but kept voting for the King from the same family and the King was enjoying his life and doing anything.

I have a question to ask. From above story, actually who was the idiot? Is the King or those intelligent people? I am sure you know the answer.
