The DNC doesn't truly provide the means for their party members to actually participate in selecting candidates to the same degree the Republicans do, and therefore they place some kind of party ideal over the democratic participation of their party members. Superdelegates, not holding a caucus primary this time, conspiring against Bernie, all that stuff. It produces manufactured candidates that don't have a real relationship to party members, not an extension of the zeitgeist. They shove square pegs into round holes and wonder why it doesn't fit.
