We need someone to step up and sponsor things like televised 3rd party only debates. Do a lot of groundwork to make it clear that "this time" a 3rd party has a legit shot, has major support and has a chance to win.Then I wouldn't vote for them and likely no one else would. We choose not to vote for bad 3rd parties candidates and force ourselves to vote for bad main party candidates.
Too late for that this time. But if some super rich ******* was all about getting a 3rd party in the mix they could start working right after this election to get some stuff going.
