Lincoln supported colonization all his life; many people did. To say that Lincoln supported deportation at all, much less at the end of his life, is a gross exaggeration of the facts.
Jefferson contemplated expulsion. Madison favored colonization. Lincoln explored voluntary emigration.
Thanks for that clarification.
IIRC, Jefferson's plans included mandatory deportation of freed-slaves.
Lincoln's idea was strictly voluntary emigration of freed-slaves who wished to leave.
I think it's fair to say that even in 1860, most people could not imagine former slaves living peacefully with their former slave-masters.
Hence plans for deportation or voluntary emigration.
