After having voted for the lesser of two evils in elections past, the way I see it (assuming you vote) there are two choices with three possible outcomes:
Choices:
1. Vote your conscience and support the candidate who most closely shares your values.
2. Vote for the lesser of two evils.
Outcomes:
1. You voted your conscience and still lost. Be honest, you knew he/she wasn't going to win in this state. You can rag on the winning candidate and anyone who voted for him/her, and even those who voted for the other lesser of two evils because they still supported a turd. But what you did was help validate an "outsider" and say "There really are people who won't vote for a less stinky turd".
2. The lesser of two evils wins and you can take pride in having voted for the winning turd. Good for you; you pulled the turd lever and won.
3. The greater of two evils wins and you can rag on them, confident in not having voted for him/her.
Notice I said "the candidate who most closely shares your values". Unless you're voting for yourself, it's not likely that any candidate will support everything you stand for.
