Fun fact! If you ask a bunch of social-science grad students—spefically St. Antony's College, Oxford—to design an electoral system they will go for ranked-choice, as we did in 1997 for student government positions. So I was elected Social Secretary (yes really) by RCV.
Lane GreeneHere's some advice: ask Americans not "do you support ranked-choice voting?" (what's that?) but "would you like to not only vote for the candidate you like most, but have a second vote against the one you hate most?" Landslide.
