“Does “the governed” also refer to the enslaved?”
No; the concept of “consent of the governed” was not a reference to slaves voting for wage and hour laws.
At least I don’t know of any signers of the DOI that argued that slaves were brought to this country to be electors.
Maybe you know otherwise.
What I know is only my belief that to argue for states rights on the basis of “consent of the governed”, whilst owning slaves, is hypocritical.
