The South's Electoral History if State Suicide was implemented?

[Huey Long is a Republican]

For those of you who don't know, following the Civil War, Radical Republicans like Charles Sumner believed that States that had seceded had forfeit their right to exist and their current borders, meaning now they could be turned back into territories and readmitted as states in a completely different form. There were rumors that several Black Majority States and pro-Republican states were planned, which would benefit the Republican Party massively for obvious reasons. But anyways, how would each new state look and how would this effect the South's electoral politics?

Zero?

Remember that Mississippi, South Carolina and Louisiana had Black majorities anyways at the time. Having all the South reverted to territory status wouldn't have produced any difference, I think. Whites would very likely have had the same reaction to Reconstruction, Republicans, federal government etc. they had in real life, and mostly the new states would have had KKK and Red Shirts and disenfranchisement anyways, unless Congress had really tried to enforce hard a Radical Reconstruction, but this caveat applies to the real life states too.

The only difference is if they had crafted a state combining Unionist Central Ky. / Eastern Tenn. / Western NC with some heavily Black areas in the Low Country. Such a state would likely have been Republican through and through and I suppose it would have enacted Jim Crow sh**t anyways but not voter disenfranchisement laws and resemble Oklahoma or Kentucky - that is, a border state - but more Republican.
