Voting for the Oscars is now over. Now comes the waiting period to see the results on Sunday night. Final predictions and the Supporting Actress Smackdown are coming up tomorrow! In the meantime, let's talk preferential balloting. This type of voting has given us some amazing winners (Moonlight, Parasite, Nomadland) but it has also given us some absurd ones (Green Book) though we can never know which would have still won on a straight plurality ballot and which would have lost. We've seen a few of these videos over the years explaining this but this is a really good one.
It's also worth noting that the other categories use a straight plurality system. The film/person with the most votes win. This balloting system is only used for Best Picture.
