The fact that your vote will not change the results actually is a great plus for you! Now you can simply vote your conscience and not have to worry about your "vote being wasted". Voting for someone or some issue that you don't really believe in is really unethical. For most people, to do so is upsetting and shameful. So, don't bother. Number 1, do your duty and vote and number 2, vote your conscience. I think you will feel a whole lot better about it.
