Clinton moves on after crucial win in Pennsylvania

Hillary Clinton yesterday hoped for momentum from her decisive victory over Democratic rival Barack Obama in Pennsylvania to show she had the broad support to win the US presidential election in November.

But Obama emerged from the latest, and most acrimonious, bout in the state-by-state contest still holding a narrow lead in popular votes and in delegates who select the party's nominee at its August convention.

Clinton told cheering supporters in Philadelphia after Tuesday's vote: "Some people counted me out and said to drop out, but the American people don't quit and they deserve a president who doesn't quit either."
