"Lincoln was nominated by the Republican Party, which had taken a public position against the expansion of slavery into the newly acquired territories. Furthermore, his personal views against slavery were well-known, and he was perceived as a strongly partisan, anti-Southern, abolitionist candidate."

But even then. not all slaves were treated equally even when free.
