An interesting point Q.

A 97 year old neighbour of mine, once told me she never voted after her husband died (when she was 75). She said that many people tried to convince her to do so, that it was her duty, but she never caved in to their persistance. The reason she gave was as follows: She said that she never followed political issues, nor the politicians after her huisband died. So, she told me that she did not wish to vote and cancel out the vote of someone who did follow such things, and would know much more than she did on the issues and the people seeking office.
