The best option that aligns with Abraham Lincoln's views on slavery, especially during the debates of 1858, would be the Kansas-Nebraska Act.
Lincoln opposed the expansion of slavery into the territories, which was a key component of the Kansas-Nebraska Act. This act allowed the territories to decide for themselves whether to allow slavery, thus effectively repealing the Missouri Compromise. Lincoln's arguments during the debates, particularly against Stephen A. Douglas, highlighted his belief that the spread of slavery should be halted, making the Kansas-Nebraska Act central to these discussions.
