(engl.: "If resistance to the Slave Power was the reserved watchword of your first election, the triumphant war cry of your re-election is Death to Slavery. [...] The workingmen of Europe [...] consider it an earnest of the epoch to come that it fell to the lot of Abraham Lincoln, the single-minded son of the working class, to lead his country through the matchless struggle for the rescue of an enchained race and the reconstruction of a social world." - marxists.org http://www.marxists.org/archive/marx/iwma/documents/1864/lincoln-letter.htm; Papers relating to the Foreign Affairs ...
