Forty-five years after Dr. King spoke on the steps of the Lincoln Memorial, I marched my old legs to the polls along with millions of other Americans to vote in an historic election. It was the first time that an African American -- Barack Obama -- had won the Democratic nomination and appeared on the national ballot for president of the United States. As I cast my vote, I thought about my grandfather Pap, who didn't live to see this moment, and my three children and two brothers, who did; I thought about my mother and father, and my aunts and uncles; I thought about Abe Lincoln, Frederick Douglass, and Harriet Tubman; I thought about presidents Kennedy and Johnson, Dr. King, Thurgood Marshall, the Freedom Riders, the marchers, and all the people who lived and died so that I might walk into this booth and cast my vote. I thought about them all and smiled; and as I walked away, I closed my eyes and said, "Thank you."

Our centuries-long struggle for freedom and equal rights had helped make the American promise of life, liberty, and the pursuit of happiness a reality for all Americans. We have come a mighty long way, honey, and we still have a good ways to go, but that promise and the right to fight for it is worth every ounce of its weight in gold. It is our nation's heart and soul.
