"If you vote for Jill Stein, you are voting for Donald Trump."
"A vote for Jill Stein is a vote for Donald Trump"
This is becoming a popular sentiment among my fellow Liberals and Democrats about those of us thinking of voting for a 3rd party candidate. And it's wrong. Not morally wrong, but logically wrong.
The simple counter-argument:
Assume: "A vote for [someone not named Hillary Clinton or Donald Trump] is a vote for Donald Trump."
1. If I were a Donald Trump supporter, I could just as easily assert that "A vote for [someone not named Donald Trump or Hillary Clinton] is a vote for Hillary Clinton."
2. The two statements together lead to the conclusion that "A vote for Donald Trump is a vote for Hillary Clinton," which is nonsensical. The only statements of this kind that are logically sound are a series of tautologies:
"A vote for Donald Trump is a vote for Donald Trump."
"A vote for Hillary Clinton is a vote for Hillary Clinton."
"A vote for the candidate I voted for is a vote for the candidate I voted for."
So please stop claiming that a vote for someone is actually a vote for someone else. The world is dumb enough as it is.
