The celebration of Martin Luther King's birthday was a little different this year. It had a political edge to it, and unavoidably so. Dr. King's work made possible what we're finally seeing today -- a black candidate making a serious run at the American presidency. So it seemed entirely appropriate that Barack Obama spoke Sunday before the congregation at Ebenezer Baptist Church in Atlanta, where MLK preached long ago. In this 34-minute speech, you get a perfect reminder of King's legacy and also a stump speech delivered in an oratorical style that King would appreciate.
