I heard it said that voting for the lesser of two evils is like the guy that beat his wife. As a defense in court he told the judge that he should find him innocent because it could have been much worse, he could have killed her.
And voting for a third party candidate who stands no chance of winning, and in fact will drain votes away from the viable candidate who is the best option, is like spitting into the wind because one does not like the weather.
How far do you want to go with this silliness?
