Everyone knows that political party power structures start from the TOP down. “Superdelegates” are people in the party structure who owe their comnplete loyalty to the party structure and so are nothing more than ‘political chips’ owned by the few TOP party people in the power structure. Its that simple.
That’s no different than the board of directors in the private sector.
Most superdelegates are so by virtue of the fact that they have won political office in general elections. They really don’t owe the party much. The Dems wanted to be sure that there would be plenty of delegates who would know how to win a general election.
