What was Abraham Lincoln's evolution?

Answer 1

I'm not sure I understand the question, but if you are asking how he changed or evolved, one big issue on which he evolved was slavery. While there is little evidence he was ever a big supporter of slavery, he at first believed in a hands-off approach, where each state would decide for itself. But as time passed, he came to believe slavery was tearing the country apart and it needed to end. By the time he ran for president, he was no longer convinced that the states should be allowed to decide; he had evolved to the viewpoint that it was time for the federal government to take a stand in ending slavery throughout the country.
