Years of lesser of two evil voting has sent us to the lesser of two genocides, and the US picked the bigger genocide anyway. How long are you going to imagine that as being a viable strategy? How many genocide only elections will it take?
History will view lesser evil voters the same way they veiw ww2 German citizens who were just doing as they're told.
Just like the pit of infinite despair and spiked dildos is technically different from the pit of infinite spiked dildos and despair; being to the left of republicans because you want to burn orphans for warmth instead of fun does not make you left wing nor a good choice.
