Me, neither. My husband hated Lincoln because he thought the Civil War could have been avoided and Lincoln enacted some government policies that were overreaching.
But Communism? Not seeing it.
I've heard of this before, but I don't put much stock in it. Karl Marx supported Lincoln because he saw what Lincoln had done as benefiting the "workers" and the poor class. There were people involved in the early aspects of communism that were on Lincoln's side and in positions of influence, but it does not necessarily follow that Lincoln's motivations were communistic.
I place his motivations as being "Crony Capitalist", not socialist. Look at who benefited from what he did. Those who gained were the titans of Northern Industry. The Rail Roads, the Shippers, the Bankers, the Manufacturers, and so forth.
Had the war not been fought, these people would have lost huge sums of money as the South "stole" much of the North's economic activity by shifting European trade to the South.
