Over the past year, Bernie Sanders’ supporters have repeatedly criticized the undemocratic role of superdelegates in choosing the Democratic presidential nominee. In February, for example, MoveOn, which had endorsed Sanders the month before, started a petition saying, “Democracy only works when the votes of the people—not the decision of a small number of elites—are what determines the outcome of elections.” The fear, then, was that Sanders would win the most pledged delegates but that Hillary Clinton would use her pull with insiders to trump the popular will.
