Nah, Lincoln killed it, and the corrupt post Civil War Supreme Courts made sure it will never come back. Republicans shot themselves in the head along with the entire country. That's why FDR is so hated by them; he made their looting and stealing a little more difficult. JFK actually helped bring it all back with his belief in 'technocracy' and big banking. By 1976 FDR's reforms were all gone, and the bubble economies and off-shoring began. We're now in a similar situation to the rest of the world that the South was compared to the North when Lincoln started his murder and looting rampage; we have a mono-economy built on debt instead of cotton, and the world's shitholes have all the factories and resources.
James Madison shut down a clause being added to the Constitution that gave the Federal govt. the power to use force against a state in 1787, during the Constitutional Convention. Lincoln and the northern financial interests didn't care about that and started a war anyway. They wanted free land, free railroads, and high tariffs.
The United States has never suffered a civil war. The so-called Civil War was a war between two nations. I call it the War of Secession.
After South Carolina seceded from the Union (which it has a perfect right to do so), and the federal government refused to relinquish Fort Sumpter, the State militia fired upon it to force the federal government to leave and return to their own country. The first shots were fired by the State Militia of South Carolina. It could be argued (and quite successfully) that those shots were fired in defense of South Carolina's sovereignty (and with it the CSA's sovereignty).
The Confederated States of America (the CSA) formed their own army and defended themselves (which they also have a perfect right to do so). The secession by various States were over violations of the 4th amendment by the federal government (slaves are considered property).
The Union won that war, and the CSA was dissolved.
Both sides were right, and wrong.
Lincoln was right in trying to preserve the Union and to restore the lost States to the Union, and to end legal slavery.
He was wrong about how he did it.
The CSA was right in trying to defend itself, and about the federal government violating the 4th amendment in the taking of private property (the slaves). It was wrong in trying to continue slavery.
Today, of course, slavery is outlawed by Constitutional amendment. The slaves and their children were given full and equal citizenship via another Constitutional amendment. The CSA is dissolved, and all former States of the CSA have rejoined the Union and have stayed with it since.
The Constitution of the United States is still in force, as amended.
Are there people that want to subvert it and destroy it? Yes, certainly. Some even in government. There always has been since the Constitution was first established and ordained as the founding document of the federal government.
But it is not gone. By and large, the people support that Constitution as amended, and they support the federal government and each of the States of the Union. Radical Democrats, of course, are NOT by and large, the people. They are a loud and obnoxious minority, quickly relegating themselves to minor party status.
