How do you think America might be different if South Carolina Exposition and Protest published during the Nullification Crisis had not occurred?
Would it be that Congress's power to create laws is useless if every state could just decide for themselves what they will or will not follow.
Or that the U.S. would be a bunch of little countries doing their own thing.
That was just one of many states's rights demonstrations over our past 250 years.
I don't think the Exposition changed history one little bit.
