To Vote or Not to Vote: Debate over Photo ID Laws Heats Up

Voter ID laws vary all across the United States. Some states require photos, while others do not. Last week, the Justice Department blocked a new law in South Carolina, requiring a photo ID, saying it would disproportionately affect minorities. Proponents say that ID requirements help prevent election fraud. Is voter fraud really a problem? What role does partisan politics play in these laws? What's wrong with having to prove who you are in order to vote? What impact do photo ID requirements have on who votes or doesn't? Do such laws interfere with one of the most basic rights of American citizenship?
