What Abraham Lincoln understood

"That's what Abraham Lincoln understood. He had his doubts. He had his defeats. He had his setbacks. But through his will and his words, he moved a nation and helped free a people. It is because of the millions who rallied to his cause that we are no longer divided, North and South, slave and free. It is because men and women of every race, from every walk of life, continued to march for freedom long after Lincoln was laid to rest, that today we have the chance to face the challenges of this millennium together, as one people - as Americans," said Barack Obama.
