Superdelegates, independents moving to Obama
Barack Obama’s march toward the Democratic presidential nomination picked up support from four more superdelegates Wednesday, pushing him ever closer to victory over Hillary Rodham Clinton — even as their primary marathon staggered on.
She added two superdelegates herself in what has become the last big contest as their race winds toward a finish.
There are just 217 delegates to be chosen in the final six primaries, and neither candidate can win enough of them to claim final victory. Meanwhile, 265 additional delegates — the party elders and other “superdelegates” — have yet to be claimed, and their support will be the deciding factor.
