We need open-list MMP or some other form of non-party-list PR. Ranked choice helps, but it still means that non-hyperlocal constituency groups can be ignored. Since old people vote in droves and there are old people everywhere, local winner-take-all systems like FPTP and yes, ranked-choice, still let the politicians ignore the youth.

Regional-proportional systems like STV or MMP let a constituency in the region that has enough people for a rep regionwide but not enough for any single riding get a voice in the assembly.

I mean, on the downside, this includes Nazis. But on the upside, this includes renters.
