Clinton calls on supporters to back Obama

Hillary Rodham Clinton told an exuberant crowd she wanted Barack Obama to win the White House, saying that even though he dashed her presidential dream he is a better choice to lead America than Republican John McCain.

The speech in Washington was Clinton’s first at a rally for Obama since their ballyhooed appearance together in June in Unity, New Hampshire, and follows news that former President Bill Clinton, her husband and one of Obama’s toughest critics during the Democratic primary, will speak on the third night of the party’s national convention.
