blacks represented 20% of our entire population and they voted almost exclusively Republican, i.e. newly elected black Representatives, notable figures like Frederick Douglas, et al. What changed? The simple answer is Woodrow Wilson and FDR. Wilson resegregated the military, FDR initiated voting requirements for blacks in order for them to gain jobs during the Depression when blacks were fleeing the rural environments for jobs in the city. "You want a job?" said the FDR administration to the blacks; "Then sign on this dotted line, or make your mark, to register as a Democrat."
