I don’t think it’s a losing battle. If anything the last Australian federal election showed not only how good Ranked Choice is at conveying voter intention, but that a meaningful number of us understand it.
The LNP stopped representing their base (perhaps in a similar way to the ALP with the Greens) which opened the door for the Teal independents.
As an outsider looking in to US politics it appears as though similar issues exist, but there are no viable alternatives. In a positive sign for democracy US voters largely rejected candidates who were sowing doubt about the elections.
