Voting for the lesser of two evils is still voting for evil.
If every single person who said they would vote third party if it wasn't throwing away their vote actually voted third party, we'd see some serious changes. Just accept that it doesn't matter one bit whether a democrat or a republican wins the election. The results will be the same. Once you accept this simple truth, you are free. Now you can vote for a third party candidate without that fear of letting "the other guy" win. Vote third party. Always. I don't care which third party. Just don't vote for the status quo.
