Which of the following best explains the role of superdelegates?

Superdelegates are delegates to the Democratic National Convention who are not bound to support any specific candidate based on the results of primaries or caucuses. They are typically party leaders, elected officials, and other prominent members of the party who have the ability to vote for the candidate of their choice. Superdelegates serve as a check on the popular vote and can potentially influence the outcome of the nomination process. Their role is to provide a sense of balance and ensure that the party's interests are represented in the selection of the nominee.
