I'm not sure if it's even possible for a third party to win an election with the way the electoral system is set up.

The only way a third party will ever be viable in a first-past-the-post system is if you infiltrate one of the two real parties and get enough candidates elected who have pledged to replace the FPTP system that got them elected and replace it with something that makes it a viable decision to vote third-party, such as ranked-choice voting.

I actually don't have anything against the concept of voting third party. But only if one of those parties will put up somebody that isn't fucking crazy. If the libertarians put up someone like Jo Jorgenson again, why would anyone vote for them?
