Voting third party changes nothing except help the Democrat or Republican you most identify with to lose.

Voting in the US needs to change first. FPTP replaced with ranked-choice, or approval, at least; the electoral college abolished; NPVIC; proportional representation in Congress.

But the big, first monster is first-past-the-post. No third party has come close to winning the Presidency since Abraham Lincoln. Please, think about that for one second. We haven’t had a serious third party contender in one 164 years. And we won’t, until we get a different election system in place. Until then, third party candidates are spoilers.
