Will So-called 'superdelegates' Pick Our Nominee?

From Common Dreams:

"Superdelegates - mostly members of Congress, governors, party officials and grass-roots activists - can back any candidate they choose. While ordinary delegates are technically committed to a candidate, superdelegates can change their allegiance whenever they feel like it.

Former President Clinton, for example, is a superdelegate - hence his vital importance to his wife’s bid for the White House. The Washington Post reports: “Clinton, former president Bill Clinton…and their allies have been working aggressively for months to court the superdelegates, drawing on old loyalties to open a huge advantage for the senator from New York in total delegates amassed.”"
