Slavery was going to end on it's own eventually. If you bother to read Charles Dickens "American Notes", he details conversations he had with Southern slave owners. The takeaway is that many of them wanted out of it, but they didn't know how to do it without causing massive upheavals. He advised them to simply do it.
That’s progress, sir! Let’s take the next step. Is it so difficult to imagine that the gentle folk sipping on mint juleps while relaxing on the veranda weren’t so confident in the future of their peculiar institution as you are today?
I don't think their prime concern was the potential loss of slavery as much as it was the absolute hatred directed at them from Liberal Northern states who regarded them as vile disgusting human beings.
Nobody wants to associate with people who think they are human garbage, but slavery was under no legal threat until at least 1896.
There is also the matter of the ridiculous levels of taxation imposed on them by the Northern states because they controlled the majority in congress.
