What was Abraham Lincoln's position on slavery during the election of 1860 and the secession crisis that followed the election?

Abraham Lincoln was a republican candidate, so the party he was part of did not support slavery anyway. But, Lincoln didn't want the expansion of slavery to continue and he did not support the idea of slavery. Although he did not support slavery, he did not propose any ideas on stopping it completely and he was not considered as an abolitionist. Slowly though, his views started to change as the Civil War came into play. His thoughts shifted completely and the only thing he supported was saving the Union. During the secession crisis, the election had just finished, so Lincoln's ideas were still the same.
