This is a modified version of c:File:2023 Australian Indigenous Voice referendum opinion polling – forced-choice only.svg with a more colour-blind friendly palette and some methodological changes significant enough I thought making a new file was worthwhile. The forced-choice only version restricts itself to only aggregating results from binary polls. However, this version also aggregates polls which pursue "leaners" by asking them a follow-up question, but still give the option to remain undecided.
