From the Clinton camp...

[S]uperdelegates were not selected by the national party to be either potted plants or rubber stamps. We were selected because under party rules that have been in place for a generation, our party concluded that we had demonstrated the ability to act as stewards of the national party--and of the national interest. By dint of our experience in the community and our public service, we were adjudged fit to fulfill a moral responsibility to act in the best interest of the country as we saw it--and to be strong enough to withstand the criticisms of those who might object to the political impact of the independent conclusions we reached.

Hmm....why do people even need to vote when you can just appoint a few wise people to choose our leaders for us? But don't worry...she's not a socialist. Nope. Never that.
