There has been some comparison of Obama to Lincoln:

He even compares himself to Lincoln:

He can't see Lincoln as the Great Emancipator? The Emancipation Proclamation was "more a military document than a clarion call for justice"? Yes, Senator, it did take a war. I guess all the clarion calls for justice Lincoln made up to that point were not sufficient.

Is Obama the next Lincoln? Is he better than Lincoln?
