During the creation of the US constitution there was a debate over how, or even if slaves should be counted for purposes of representation. One hilariously insulting idea was the 2/3rds idea. The compromise that won over all the others was the sunset clause. The central idea was any one born on US soil after 1847 would be born free, with slavery dying a natural death.

How would america change as a country with out the sunset clause? Would free states try to block states from joining the union? Would the economy of the south be different? Would there be more slave revolts?
