That Lincoln studied Marx is a myth that has circulated off and no for years.
That Lincoln had even heard of Karl Marx is doubtful, and there has never been any evidence found that he had.
But the fact that Lincoln was a socialist, there is no doubt. Like Obama, he was a one term congressman, but in the realm of chaos, and Constitutional destruction, Lincoln made Obama look like a Sunday school teacher.
Lincoln with the support of lobbyists for the "industrialized North, and with the use of the United States military, is guilty of the killing of almost 1 million Southern men, women, and children, destroying homes, farms, and burned entire cities.
Allegedly for the "preservation of the union", and freeing the slaves.
Ending another myth that if order, the United States military would not fire on United States citizens.
Quite an accomplishment of being called "The Great Emancipator" after such a slaughter of humanity, and the destruction of cities, towns, and families.
