Voting your conscience is -by definition- wasting your vote. Arguably it's the only guaranteed way to do so. The vote does not care about your conscience. The ONLY thing that matters in an election, is who holds power after it is over. You either vote in such a way as to ensure the best outcome or you don't. If your vote helps keep the Con/PPC out, you did right. if it does anything else instead, the vote was wasted. You don't get extra good boy points for voting for someone who has no chance of winning and helping the bad guys win instead. In fact is kindof makes you a dick because you are prioritizing your ego over the well being of others.
