A "superdelegate" or an "unpledged delegate" is a delegate to the Democratic National Convention or Republican National Convention that is seated automatically, based on his or her status as current (Republican and Democratic) or former (Democratic only) party leader or elected official. Other superdelegates are chosen during the primary season. Democratic superdelegates are free to support any candidate for the nomination. This contrasts with convention delegates that are selected based on the party primaries and caucuses in each U.S. state, in which voters choose among candidates for the party's presidential nomination.
Although "superdelegate" was originally coined and created to describe this type of Democratic delegate, the term has become widely used to describe these delegates in both parties, even though it is not an official term used by either party.
Bernie and Donald are both in trouble. Super-delegates favor DC insiders. The smoke-filled room still exists.
