This site answers the question "How do you become a delegate to the 2008 Democratic National Convention?" Features an overview of the types of delegates: district-level, at-large, add-on, and party leaders and elected official (PLEO). Some of the add-on and PLEO delegates are unpledged, and are known as superdelegates in the media. Also includes an interactive delegate map, and a link to the 2008 delegate selection rules.
