I’ve been considering a hypothetical scenario where the CSA is oriented more towards the areas west of the Mississippi. Perhaps Virginia votes not to secede and therefore keeps Tennessee and possibly North Carolina and Arkansas in the Union. But on the other hand, Kansas is admitted as a slave state, the pro-slave coup in Missouri succeeds, the Confederates are more successful in seizing control of the Indian and New Mexico Territories, and (if it’s at all possible) CSA sympathizers in Southern California break away, splitting off part of the state to join the Confederacy. Is this a plausible scenario? How does it affect the course of the war?
