Not looking for a PR discussion, or to discuss incompetence or fraud by elected officials. Really just aiming for a semi-serious discussion of the likelihood of an individual's vote actually making a difference to the outcome of a constituency election. As far as I can see, only a fraction of recorded elections come down to a knife-edge result - say 2%. Within this 2%, the error in counting votes is >+/-1 vote. Therefore, if you, as an individual, just walk into a polling station and mark your ballot, chances are that you make no change to the final outcome. The only way to make your voice heard in an election campaign is to influence other people to vote the same way as you - in a close run seat - and to a number greater than the error of the vote counting method..? Is that fair? Anybody care to populate this discussion with further numbers or ideas?
