Who are to be the electors... ? Not the rich more than the poor; not the learned more than the ignorant; not the haughty heirs of distinguished names, more than the humble sons of obscure and unpropitious fortune. The electors are to be the great body of the people of the United States.
The ability to read and write . . . has some relation to standards designed to promote intelligent use of the ballot.... Literacy and intelligence are obviously not synonymous. Illiterate people may be intelligent voters. Yet in our society where newspapers, periodicals, books and other printed matter canvass and debate campaign issues, a State might conclude that only those who are literate should exercise the franchise.
