It absolutely makes sense. You need buy in from the public. RCV is the most known alternative and it has taken a decade to get it that far. If you want to start the work of informing people about STAR voting then be my guess but RCV is a tremendous improvement from what we have and an acceptable alternative.
Most people don't actually know anything about any of this. If they've heard of RCV at all their understanding of it is at the level of "it's something different than the status quo and supposedly better". You could swap in STAR and they mostly wouldn't even notice that you've changed anything. But you'd notice the difference in the election outcomes, in a good way.
Personally I think “approval voting” is almost as good as RCV but orders of magnitude easier to sell to the public.
There’s just a checkbox next to each candidate and you check the box next to any candidate you’re “okay” with. Results in the most “okay-est” candidates getting elected so when the winner is announced everyone goes “…okay.”
Also could make primaries less important, because multiple candidates from a party could theoretically run for the general election without splitting votes.
Communication is easier because in RCV the candidate who gets the most #1 votes doesn’t necessarily win which could lead to a loss of confidence in the system. Its very easy to tell the American public “this guy got the most checkmarks” and no one gets confused.
