A new study says Idaho's voter ID law, and similar laws in 13 other states, will make it harder for nearly 5 million people to vote in 2012.
The study by the Brennan Center for Justice at New York University School of Law said 19 laws and two executive orders requiring voters to show photo identification at the polls limit access.
"The whole issue of access to the polls has become politicized in a way we haven't seen in the past," said Lawrence Norden, director of the Democracy Program at the Brennan Center. "If you're poor and you don't have a birth certificate or credit card, then it becomes extremely difficult to get those things so you can get out and vote. Some of those people are going to get ID and be able to vote, but some of them aren't."
"Five million voters is considerably more than the margin in two out of the last three presidential elections," said Michael Waldman, executive director of the Brennan Center. "These kinds of rules matter enormously. If this is a close election, as it may well be, these voting rules can turn out to be quite significant."
