OK, I’m not backing Trump, but who runs such a poll and why? The answers are obvious.
There are many things that WOULD be different and perhaps better had the South cessation succeeded, especially if it had done so without a fight.
Had Lincoln allowed the South to split, we would have had two countries for awhile, maybe forever, but we would have remained closely tied. The “United States are...” would have remained the rule of the republic, and states rights would have prevailed.
The heinous practice of slavery would have continued in the South for perhaps another 20 years, but then it would have had to come to an end. The United States and the Confederation would have likely stayed out of WWI and after the termination of slavery, the two would likely have come back together before WWI.
Germany would have likely terminated WWI on far more favorable terms, meaning Bolshevik Russia and NAZI fascism might have never existed.
What we do know is that after the Union victory, state’s rights because non-existent and Southern blacks continued to live as less than equal citizens for 100 years.
I made that exact same point to a man who alleged that subsequent history would have been worse than it turned out to be.
My only response to this assertion is "Really? How? How could it have been worse?
