In addition to seeing who voters may support if their top choice drops out (or is eliminated during an RCV count), a ranked poll provides opportunities to learn more about the breadth of support each candidate has. For instance, the below chart shows how many voters ranked each candidate in each position.
This chart indicates different depths of support for different candidates. For example, candidates like Sanders, Biden, and Bloomberg have many first- and second-choice rankings. Candidates such as Gabbard and Steyer appear more frequently as sixth- and seventh-place rankings.
