Same as I wrote on the other sibling comment. I think these countries all have terrible electoral systems. But the point is, they’re still ahead of the USA in terms of the fact that they will still have an awareness and understanding of third parties, whereas >90% of Americans are just programmed to believe there are only 2 options.
As a thought experiment, ask yourself what would happen if you could wave a magic wand and make every city, state and national legislative election use RCV over FPTP. Do you really think anything would change? I’m pretty sure 95% of the results would be exactly the same. Like I said above, RCV may make things better 20+ years from now, but there’s also a very good chance that so few people actually use their second options that it nothing ends up changing at all. This is why I think multi-member districts or MMP are better solutions.
