Graduated majority judgment

Graduated majority judgment (GMJ), sometimes called the usual judgment or continuous Bucklin voting, is a single-winner rated voting rule that selects the candidate with the highest median score. It was first suggested as an improvement on majority judgment by Andrew Jennings in 2010.

GMJ begins by counting all ballots for their first choice. If no candidate has a majority then later (second, third, etc.) preferences are gradually added in, continuing until one candidate reaches 50% approval. The first candidate to reach a majority of the vote is the winner.
