Answer

Ranked-choice voting (RCV) has been around in the US for much longer, first gaining real traction after the 2000 election with Gore supporters claiming it could have helped eliminate Nader as a spoiler. It is also a relatively straightforward way to vote, despite adding some complexity and increasing cost: ranking best to worst. Unfortunately, the process for how a winner is chosen is not so straightforward. RCV often fails to elect the most consensus candidate because its counting algorithm is complex and fails many criteria voting scientists use to measure a good method.
