The consent of the governed?
Like the millions of slaves held in bondage?
Do not attempt to appeal to that which the South (Calhoun/Dred Scott) had rejected, the principle that all men are created equal and have the God-given right to life, liberty and the pursuit of happiness.
No, like the millions of southerners who explicitly indicated that they no longer wished to be governed by Washington. A slave revolt is another matter in itself and has no bearing on whether or not the southern states consented to be governed by D.C.
