About the Data

To illustrate how ranked-choice voting works, CNN conducted a survey with SSRS asking 974 Americans to rate their top five ice cream flavors from a list of ten. First choice results showed Americans have no consensus favorite: Just 17% rated vanilla first with 14% picking chocolate, 13% cookies and cream and 10% mint chocolate chip. After reallocation, though, vanilla floated to the top with 53% of overall ballots and chocolate in second at 47%. Results from the survey were incorporated into the interactive. Results shown above also incorporate preferences from people who used the interactive.
