The Chair of the Democratic party (google for any number of sources): WASSERMAN SCHULTZ: Well, let me just make sure that I can clarify exactly what was available during the primaries in Iowa and in New Hampshire. The unpledged delegates are a separate category. The only thing available on the ballot in a primary and a caucus is the pledged delegates, those that are tied to the candidate that they are pledged to support. And they receive a proportional number of delegates going into the — going into our convention. Unpledged delegates exist really to make sure that party leaders and elected officials don’t have to be in a position where they are running against grassroots activists. We are, as a Democratic Party, really highlight and emphasize inclusiveness and diversity at our convention, and so we want to give every opportunity to grass-roots activists and diverse committed Democrats to be able to participate, attend and be a delegate at the convention. And so we separate out those unpledged delegates to make sure that there isn’t competition between them.
