To add, in 2024 the 3rd party candidate with the most votes was magician Jill Stein, who magically appears right before elections, then magically disappears again afterward. And she got a whopping half of a single percent of the total votes cast.
So yeah, ain't no 3rd party going to win a federal election anytime in the near or remote future. And ain't no 3rd party even really trying. So why fucking vote for them?
