How did abraham lincoln ensure that border states supported the union?

To ensure border states remained in the union, he never said his goal was to end slavery, only that it was to save the union.

Abraham Lincoln insisted that his only goal was to save the union, not end slavery.

Lincoln's concern was to save the Union, instead of saving or destroying slavery. Lincoln would save the Union the shortest way he could under the Constitution and by using extra constitutional means. In other words, he aimed to save the Union at any cost, towards slavery.

Lincoln wrote a letter pertaining to the Union and slavery basically claiming that he believed that the Union could be saved without destroying slavery.

the fifth and fourteenth amendments to the united states constitution each contain a due process clause. due process deals with the administration of justice and thus the due process clause acts as a safeguard from arbitrary denial of life, liberty, or property by the government outside the sanction of law.
