A lot of people who are dissatisfied with the American political system have suggested ranked-choice voting.
I cannot find any polling where the people are asked, "What if the presidential or congressional election were done by ranked-choice voting: what would be your vote?" Do you know of any?
This would be curious. I find it hard to believe that no political science department in the whole of the USA took the trouble of attempting to find out.
edit: same question applies to STAR voting, or proportional representation, or other methods
