Twelve people in Alamance County, North Carolina, could go on trial as soon as next month for the crime of voting while ineligible. One of them, Whitney Brown, is arguing that the state's longstanding ban on people voting while on probation or parole for a felony conviction is discriminatory and unconstitutional. Brown makes the case that the ban was enacted by white supremacist legislators in 1900 with the goal of erasing African-American voters' gains in political power after the Civil War.
