It's the same force at work now that was at work then.
Sure, I "get" that you wish to change the subject.
But the important point to remember is: for nearly all of 72 years, from 1788 until the end of 1860, Southern Democrats ruled in Congress, in the Presidency, the Supreme Court and US military.
Of course, they did not rule alone, but with the willing, subservient & corrupt cooperation of their Doughfaced Northern Democrat allies.
These are the people you now pretend were their masters, but that's just rubbish.
The reality was that for nearly all those 72 years, Southern slave-holders dominated Southern Democrats, and Southern Democrats dominated Northern Democrats who together dominated Washington DC.
Until you grasp that basic fact, all the other nonsense you've been spewing out is just, well, nonsense.
