As a follow-up to the question of whether voting for a third-party candidate in a safe state is justified, here's a nice map of where one could vote third-party and have no qualms about how that might affect the outcome even in a close race:
That's most of the country. And if you have an election where even the third-party candidates are unacceptable (as we do now), then obviously the write-in option is available in, I think, just about every state.
I don't expect this to affect anyone's position either way, but it does speak volumes about how absurd and outdated the electoral college system is.
