Why doe the Clintons call them Automatic Delegate...?

Supposedly, the correct term is "automatic delegate", meaning they are automatically a delegate by virtue of position, and the term "super delegate" was just the colloquial term that people used. Some in the party became concerned that the colloquial term was misleading and contributing to dissatisfaction among the party members and misunderstanding of their role, and so they are trying to encourage use of the "proper" term.
