Hey Sweater Vest read up on your Lincoln. He ran for POTUS in 1860 to stop the expansion of slavery not to roll it back. Lincoln did not end slavery during the Civil War in the border states that stayed in the Union. Lincoln knew it would take a constitutional amendment to end slavery which is why we have a 13th Amendment. So I would say Cruz is much more in tune with Lincoln’s thinking then you.
You are correct. Lincoln’s Emancipation Proclamation was completely crafted as a wartime measure, based on the President’s role as commander in chief of the armed forces. It was a measure to win a war, within the president’s constitutional powers. More permanent measures were enacted within a constitutional framework.
