I think it was resolved, but then Johnson got elected, pardoned the entire Confederate South including Jefferson Davis, and rolled back reconstruction. And the south benefited from electoral success by counting the slave population toward their number of representatives despite disenfranchising them.

I don't have a real end point or pin to this thought but there's solvable electoral process things that could change the outcomes. The upsetting thing right now is disenchantment in the power of procedures to affect outcome which (1) in some sense is just an unfortunate truth but (2) in another sense is a self fulfilling prophecy as we lose touch of how processes can control outcomes.
