We just went through a simple first-past-the-post election in the US that a significant percentage of voters believe was rigged. This is the simplest system imaginable, the data is easily available to verify it was not rigged.
Do we really think the average american will be able to grok how ranked-choice voting works? Imagine for a moment the reaction from people when their candidate appears to be "winning" and then ends up 3rd after the "recalculation."
I feel like the first priority of a voting system needs to be transparency and being easy to understand, RCV isn't that. Maybe works well on small scale, I highly doubt it's a good idea nationally.
