Challenges to voting rights in this country, like the ones we’ve seen recently, are hardly a 21st-century invention. Entrenched groups have long tried to keep the vote out of the hands of the less powerful. Indeed, America began its great democratic experiment in the late 1700s by granting the right to vote to a narrow subset of society — white male landowners. Even as barriers to voting began receding in the ensuing decades, many Southern states erected new ones, such as poll taxes and literacy tests, aimed at keeping the vote out of the hands of African American men.
