Yes, voiting has some evil parts.

I can remember when class votes for best candidate to presidency.

First thing to consider is - not everyone can be nominated. Most people vote, and can't be chosen. This leads to stratfication.

5 people for this candidate, 5 people for this and 10 for this. This will give you understanding that someone is more likable than you. Some people have more friends.

Election power lead to subconscious understanding that he has rights to do something, but you can't do this. Its hierarchy. Simple logic - he is more likeble - most people think that he is the best - less people oppose.
