Lincoln was conceiving the United States that had been merely United States. In that he was targeting the Confederate oligarchs who had maintained a minority rule and a federal government that secured the rights of all people. In their view government must not be the peoples' unless it serves the interests of the few who are competent to decide for the collective. Reverting to claims of State's rights was their means to secure power in the hands of the few thus insuring that the will of the people could not interfere with their cultural claims and financial interests.
It is the combination of these two Confederate features that has once again seized control of our system. The minority means to govern and if they cannot govern with the consent of the majority or use the system to secure their power, they mean to rule by any means. Should that process fail to maintain their power they have demonstrated the willingness to use violence. Rule over the majority by intimidation and force are key elements of fascism.
It is no small irony that the current Republican Party and the illegitimate and corrupt Court that imposes their will over the majority mimic the interests and agendas of the Confederacy that Lincoln brought to defeat. At some point I think the impositions of minority rule will once again not only splinter us but will bring the kind of civil unrest and protest that we may not be able to resolve using the mechanisms of liberal democracy.
As rights are taken away---and Roe is just the beginning of that dismantling---people will actually come to realize more palpably the oppression that the minority means to impose. There is a forthcoming ruling of the Court that will likely effectively eliminate the ability of the federal government to delegate regulations to agencies, thus wrecking havoc on the EPA, FDA, well, all of it. The rules will somehow belong to the States where business oligarchs will make sure, as they have with guns and climate, that the majority's will has no power.
