How did Waring Howe, Jr., a personal injury attorney running a one-horse practice in South Carolina, become one of the most sought-after men in Democratic politics? By becoming one of an elite group known as the “super delegates.” WORLD’s Jamie Dean reports:

The 796 super delegates comprise about 20 percent of the 4,049 delegates sent to the Democratic nominating convention this summer, and they hold unique power. he majority of convention delegates are elected by state parties and are considered “pledged delegates,” which means they must vote in the nominating convention for the presidential candidate who won their states’ primaries. When a candidate wins a state primary, the delegates he or she picks up are pledged delegates.

But super delegates, or “unpledged delegates,” are considered free agents: They aren’t bound to their states’ choice for a nominee, and they may commit support to any candidate they choose at any time during the primary season.

With state primaries seesawing between Senators Obama and Clinton, people like Howe may hold in their hands the futures of some of the most powerful people in politics.
