"We affirm that these ends for which this Government was instituted have been defeated, and the Government itself has been made destructive of them by the action of the non-slaveholding States. Those States have assume the right of deciding upon the propriety of our domestic institutions; and have denied the rights of property established in fifteen of the States and recognized by the Constitution; they have denounced as sinful the institution of slavery; . . ."
"A geographical line has been drawn across the Union, and all the States north of that line have united in the election of a man to the high office of President of the United States, whose opinions and purposes are hostile to slavery. He is to be entrusted with the administration of the common Government, because he has declared that that 'Government cannot endure permanently half slave, half free,' and that the public mind must rest in the belief that slavery is in the course of ultimate extinction." - South Carolina's Declaration of Secession
The southern politicians were disappointed with the results of the election and had to move quickly to prevent the "ultimate extinction" of slavery. There was no time to waste with litigation. That could take longer than a war!
We were discussing the constitutionality of secession, were we not? You appear to be in need of a little rest: your comments are making even less sense than usual...
