Thanks for the thoughtful response. I agree that there are other structural challenges in the way of making additional parties really viable. My theory is that changing from FPTP would sort of break the ice and allow other parties to gain momentum, normalize the idea of other parties not being totally fringe, and maybe pave the way for some other enabling changes once it’s no longer strategically a terrible idea to vote for the candidates you prefer but almost certainly won’t win. It’s not the only change that would help, to be sure.
