What might we have seen from Lincoln's second term had he not been assassinated?

President Abraham Lincoln was sworn in as President of the United States of America in March of 1861 to a divided nation. He entered office facing the most existential of crises in American history: the Civil War. His leadership helped bring about a Union victory, and his leadership reunited the broken nation. Unfortunately, he President Lincoln was assassinated months after his re-election and the concurrent Union victory. This left the hefty task of Reconstruction up to his Democratic Vice President Andrew Johnson. The new President was highly unpopular, culminating in his impeachment.

What policies would President Lincoln have enacted had he been able to serve his full second term? How would Reconstruction have been approached? How would he be remembered?
