You’re only able to choose two options, how is that democracy? I thought democracy was about being able to choose anyone you think is suitable to be a leader, not one of two pre-selected people. At that point, it’s not much different to a one-party system, just with two people rather than only one person.
I think rank choice will result in third party but it will take some time. Our republic system does make it slower though compared to parliamentary systems.
I appreciate your optimism, but I do not share it and have seen no evidence to support it.
