What arguments for Constitutional ratification would South Carolina slaves have supported?

yes

Frankly, I can think of no reasons that any slaves would care whether the Constitution was ratified. The conditions of slaves were not affected by the Constitution.

To understand an argument that slaves from South Carolina might support for the ratification of the Constitution, it's important to remember the historical context. Slavery was deeply entrenched in the Southern states during the drafting and ratification of the Constitution in the late 18th century. While it is challenging to speculate on the opinions of enslaved individuals directly, we can consider an argument that slave owners or supporters of slavery in South Carolina might have made at the time.

One possible argument would be based on the Three-Fifths Compromise, outlined in Article I, Section 2 of the Constitution. This compromise stated that enslaved persons would be counted as three-fifths of a person for the purposes of determining a state's population for representation in the House of Representatives and also for calculating taxation. This compromise benefited Southern states with a significant slave population by increasing their representation in the federal government.

Supporters of slavery in South Carolina might have argued that ratifying the Constitution would give them greater political influence and leverage within the federal government. They could have claimed that increased representation would allow them to protect and preserve their economic and social institution of slavery. By giving slaveholding states like South Carolina more power in the federal government, it may have been argued that their interests and way of life would be better represented and preserved.

However, it is important to note that the perspective of enslaved individuals themselves is absent from historical documents, as their voices and opinions were often suppressed. The institution of slavery was inherently oppressive and violated human rights, regardless of any arguments made to defend or justify it.
