Thanks for the clarification. I updated our polling post to be more explicit about what the Foundation would do in that event:
([Edit/Update, January 24] In the event that the poll results do not constitute a clear community consensus, the Foundation will engage in a run-off poll (with the same constituency on Helios) to measure sentiment between leading options. This should only be an issue for Questions 2 or 5; if a single option doesn’t get 50%, the Foundation will pick the two options with the highest votes to appear in the run-off.
@sonya is correct that the Foundation will continue to use the combined forum participant + community advisory panel constituency as the basis for evaluating community sentiment.
