ok this has likely come up before but what would be the affect of a Radical Reconstruction of the American South, with say the Ironclad oath over the whole south? any thoughts?
Blacks and poor Whites are significantly better off. IIRC, some of the Radical Republicans were planning on land reform, breaking up the landed estates and distributing them to blacks and poor whites across the South. If that happens, the GOP is going to be competitive, if not dominant in the South, which may end up killing the Democratic Party itself.
The Democrats are still a major player in the north - they'd probably be even more successful if the radicals push through a harsher reconstruction.
