Before 2006, not a single US state required voters to show identification before marking a ballot. But now, 30 states have enacted some sort of voter identification law. Are these laws necessary to prevent voter fraud or are laws being passed to discourage low income groups, the elderly and minorities from voting? Lawyer2Lawyer co-host and attorney, Craig Williams, joins Professor Richard L. Hasen, from the University of California, Irvine and Wendy Weiser, Director of the Democracy Program at the Brennan Center for Justice at NYU School of Law, to talk voter ID laws in battleground states, voter purges and the potential impact on the upcoming election.
