In this edition of Legally Speaking, we explore the law and the effect of state voter identification laws that are sprouting up around the country. Several Republican-controlled state governments have been pushing laws that require voters to provide a photo ID every time they vote. We talk to Avi Green, executive director of MassVote, about how these have come about. And for a deeper discussion we go to Wisconsin, where the League of Women Voters is filing a lawsuit challenging one such voter ID law. We talk to Lester Pines who is drafting the complaint and Richard Esenberg, a professor at Marquette University School of Law who has spoken on behalf of the law.
