I'm wondering why the Communists necessarily have to come to power via coup or revolution and not via balloting, albeit perhaps with some rigging. Also, I don't like your lists because even in OTL Communist states, there was a (nominal) head of state who was a figure separate from the First Secretary of the Party.
Thank you for the response Wendell!
In my story at least, the Revolution happens in the middle of TTL Great War, when the Redneck coalition takes advantage of most of the CSA's Army being on the frontlines to rebel and take control of the Deep South.
As for the First Secratary, I thought that was what the head of state was called in a Communist Country. If that is not the case, what should the title of the Confederate Communist Chief Executive be?
