I have to say, on the whole "throwing your vote away" bit, I think you ARE throwing your vote away if you don't try to get the word out and get people to change their minds. People have free will. Just because someone is more popular in a location does not mean that popularity cannot change. But if all you're going to do is vote, and not say anything about it, at least to people you meet day to day, well then, yes, you're throwing your vote away. A 10% margin, as in the earlier example, is not that big. 10% can change in the course of a week or less. Plus polls are not perfectly accurate, and can, in fact, be completely wrong. Such a fatalistic attitude is what will hurt you.
And has everyone forgotten write-in votes? You have more options than even the third party candidates. There are MILLIONS of eligible persons. If enough people don't vote for the two main candidates, even if they don't all vote for the SAME alternative, that will be noticed, and will have an effect on future elections.
