With Edwards dropping out of the Democratic race for president, the chances of a brokered Democratic convention seem radically reduced. Either Obama or Clinton is very very likely to receive enough delegates to claim the nomination.

UPDATE: However, superdelegates could still make the convention at least a little uproarious if neither Obama nor Clinton have a commanding majority of primary delegates. As this WaPo story points out, superdelegates can switch their allegiances at any time. With 800 superdelegates (and 2025 delegates needed to gain the nomination), there's still a fair amount of room for uncertainty.
