Look it up.
You'll find one letter from Marx congratulating Lincoln on his reelection and supporting abolition.
You'll find one response to Marx, not from Lincoln, but from the US ambassador in London, thanking Marx for his kind words."
NKP_Vet: "He destroyed the government that our Founding Fathers fought and died for."
No, if anyone, that would be 1860 Deep South Fire Eaters declaring secession and 1861 Confederates who provoked, started, declared & waged war against the United States, in Union states.
But the fact is that by the end of Reconstruction in 1877, except for the 13th, 14th & 15th amendments, the Federal government had returned to pretty much its stature of, say, 1860.
NKP_Vet: "A two-bit railroad lawyer with no scruples doing the bidding of the NE Industralists who controlled the government."
Now there's your Lost Cause Marxist speaking like a true left-winger.
The fact is, Lincoln had tons of scruples, and until March, 1861, Democrats controlled the swamp in Washington, DC, beginning in 1801.
Democrats held the DC purse strings, Democrats doled out Federal largess and the single greatest US industry, by far, lined up solidly in support of Democrats -- cotton growers & NE clothing manufacturers.
Those are the people thrown out of power by the 1860 Republican victory -- they were not Lincoln's supporters, but opponents, Democrats who then, just as since 2016, went berserk when they lost their privileged position in Washington, DC.
Republicans then as now were all about rural & small-town farmers, businessmen, professionals & "wide awake" evangelicals.
