What's more surprising is that Lincoln responded. The president instructed the U.S. ambassador in London to write back to Marx and the IWM, saying he was grateful to receive support from "friends of humanity and progress throughout the world." If you're feeling like calling up the ghost of Joseph McCarthy because Honest Abe was secretly a pinko commie bastard, keep in mind that Lincoln needed the support of the British working class. They were struggling to survive the cotton shortage resulting from the Southern economy collapsing, and if England had suddenly said, "You know what? We're fine with American slavery, actually," the North would have been in huge trouble.
Lincoln may have also recognized Marx's name from his work for The New York Daily Tribune, a Republican newspaper. In fact, Marx was so connected to the U.S. that he seriously considered moving there. He applied for a visa to immigrate to Texas along with a wave of Germans heading there after the failure of the 1848 revolutions.
