Agreed, but it’s only under fairly specific circumstances that it’s effective (i.e. worth it for the rational voter) in such a system. Post-war Britain managed to delete the Liberal party (or maybe just rename) but they ended up in the same boat after a while. If you can’t respect ranked preferences you end up with two big parties that try to represent a bit more than half the country, with all the nuance that allows.
That’s all true, yes. I just think it’s rational to vote third party if you were planning on not voting at all because it has some positive benefits and no real downsides.
