If no one supports third parties third parties will never have support. Ultimately campaign finance reforms that allow third parties to have a platform is what I’m looking for. The solution is a long game that not enough voters are interested in playing, but it starts with picking people within the two party system that are willing to make some basic reforms (financing and RCV) that can make room for more diverse candidates.
Your nihilism brings nothing but more of the same clown shows that we have currently.
