addendum:
the #USA is a two party system due to shitty #FPTP (unlike FPTP #UK or #Canada with #parliamentary systems that lend third parties stability)
meaning it's just math
if we removed all the corruption by magic, and we'd still have only two parties
the solution is #rankedChoiceVoting, which is creeping in. after #RCV, we can vote 3rd party to our hearts content. i will
but *before* that switch voting third party only splits the left vote and helps #fascism win
