In some cases, white conservatives in the south attempted to defeat congress reconstruction plans by boycotting the polls. In addition, the southern states were overpoweringly democrat so by readmitting them as states the republicans were probable to fail their main stream in congress. The differences between the conservatives, radical and modern factions of the republican party during reconstruction are conservatives that south should ratify the 13th amendment but not much else to be readmitted. Radical that they not just ratify the 13th amendment but that the union troops remain in the south to impose new rules. Moderates required some rights for blacks but did not agree with the radical method of violence and punitive measure in contradiction of the former confederates.  

Why do you have to ask such hard questions.
