In some presidential elections, superdelegates can play a major role in determining the Democratic nominee. Unlike delegates, superdelegates are not bound to represent the popular vote of a region at the Democratic National Convention; they are free to support any candidate for the nomination. The Republican Party does not have superdelegates.
Another difference is that there are some delegates (called unpledged delegates in the Republican system and superdelegates in the Democratic system) who are not bound by the results of the caucus or primary in their state. They are free to vote for the candidate of their choosing.he caucus system was the original way in which political parties chose candidates.
