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.

Since I must assume that you are not stupid, I have no choice but to be insulted that you think so little of the HN audience that you expect we would become convinced of your assertion after reading that statement.

Thank you for the substantive reply. Cheers!
