Imagine you're confronted in the street by a bully who insists you “make a choice": "Do you want a punch in the nose, or a poke in the eye?”
Isn't choosing either one or other wrong? By choosing either, says the Tomahawk Kid, you are giving them your permission to do both!
So if you wouldn't make that choice, why do you vote for the lesser of two evils? Isn't it the same?
The only wasted vote is a vote for someone who's going to do you over.
