"Lincoln and the Republican Party of the 1850s were able to mobilize a national majority against the expansion of slavery only because of the commitment the founders had made to the proposition that all men are created equal. The Republican opposition to slavery led to secession and civil war. After the border slave states had become committed to the war effort Lincoln took his earliest practical opportunity to announce the Emancipation Proclamation. From then on, the war for the Union became a war to abolish slavery... The founders believed that their compromises with slavery would be corrected in the course of American history after the union was formed. Their belief turned out to be true, although the new birth of freedom proved to be less inevitable and more costly than they had anticipated. The civil war fulfilled the antislavery promise of the American founding. Lincoln was right, and today's consensus is wrong. America really was 'conceived in liberty, and dedicated to the proposition that all men are created equal'. Under the principles of the declaration and the law of the constitution, blacks won their liberty, became equal citizens, gained the right to vote, and eventually had their life, liberty, and property equally protected by the law. But today the founding, which made all this possible is denounced as unjust and anti-black. Surely that uncharitable verdict deserves to be reversed."
