Obama, Clinton to campaign in Philadelphia

March 17, 2008 8:55:17 PM PDT
Barack Obama will deliver what could be the most important speech of his campaign today. The speech will be about race, and specifically, about his long-time pastor, the Reverend Jeremiah Wright.

Obama is trying to distance himself from Wright's provocative and seemingly anti-American sermonizing that has been all over television and the Internet.

Hillary Clinton will also be campaigning in Philadelphia at an event in Center City.

Her staff opened a new field office in Allentown on Monday.
