Superdelegates

The Iraq War is one issue driving up voter turnout in this year's presidential campaign. So far, more than 25 million Americans have cast their votes in the Democratic presidential primaries and caucuses alone. But when all the voting is done, neither Barack Obama nor Hillary Clinton is likely to have enough pledged delegates to win the nomination. In the end, it will probably be up to some 800 Democratic Party insiders -- the superdelegates -- to put one of them over the top. California has 71 superdelegates, more than any other state -- and they're being watched like rats in a clinical trial. Reporter: Scott Shafer
