The Fifteenth Amendment and "Political Rights"

Professor Xi Wang has offered us an altogether exemplary paper on black suffrage. Rather than trying to criticize it, I shall attempt to extend it by picking up where he left off. My main text is the Fifteenth Amendment. I would like to suggest that the best interpretation of the Fifteenth Amendment would read it as encompassing a cluster of political rights; the Amendment protects not only the right to vote, but also the right to hold office, the right to be voted for, the right to vote in a legislature, the right to serve on a jury, and even the right to serve in the military.
