The Superdelegate

Just when I thought that I had finally understood most of the American political process, I came across the super-delegate today in class. Just in case there is anyone else out there who got thrown off by this, a super-delegate is a delegate that is not chosen by the primary or caucuses in each state, but is seated based on their current or former office. Most importantly, they can support any candidate for nomination. After reading this up, I am surprised that there has not been much coverage or mention on the super-delegate in the press, especially seeing as how close it is getting on the democratic front... maybe someone can help shed some light on this?
