“Superdelegates, put simply, are a bad idea for a party that consists more of a combination of demographically based interest groups than a consistent ideology.”
Yes, the Democrats are a collection of various interest groups, or groups that have a grievance/victim mentality about their place in society.
I’m not sure about the Republicans unified party ideology sometimes, but I think it’s true that, if you consider yourself a member of a group that has grievances and has been allegedly victimized by society or goverment, chances are, you are a Democrat.
Maybe, but human nature being human nature, and politicians being politicians (of whatever ideological stripe), this "Superdelegate" (read: elitist) concept just rings of anti-democracy .. the will of the people be damned. I don't hold with it.
