What if the American Civil War happened four years later(under President Fremont)??? The upper South stays in, but a pro-"Confederate" assassin from Virginia kills Fremont a few months into this war(he promises to end slavery at the start of the war) and there is a revolution by slaveholders. After this, a junta takes over. Although they do easily abolish slavery and win the war quicker than OTL, they do so more brutally, and do the land redistribution, and create new states like East Tennessee and North Alabama. Democracy does return a decade later, but a very different constitution(think the French Third Republic, elements of the Kaiser' Germany{which had a democratic lower house}, or any constitution written in the late 19th century OTL), and a leftward shift. Although still quite racist, there is no Lost Cause{ a weaker Jim Crow appears, but voting rights are left alone}, given there is little to romanticize given the North was divided and the South was extremely weak.
