The constitution only added the word “male” with the 14th amendment. Before then who could vote was up to the states. Indians were full citizens or not, depending on their tax status. The Rolf family, descended from Pocahontas, had long been important in Virginia. Assimilated Indians voted. Why would they not?
“Up to the states”...........and that was the fundamental concept that guided the development of the Constitution, and especially the Bill of Rights.
It was also the fundamental underpinning of the Confederate Constitution.
