(CBS News) Closing arguments got underway Thursday in a lawsuit challenging Pennsylvania's new photo voter identification law. The outcome could determine if voters are required to present a photo ID at the voting booth on Election Day in November.
After Pennsylvania Governor Tom Corbett signed the measure into law in March, voter advocacy groups, including the American Civil Liberties Union and the NAACP, quickly challenged it. They said the law will deter elderly and minority voters, who are less likely to have photo identification, from voting. These groups tend to vote Democratic. Proponents say the law will prevent voter fraud.
The week-long case included testimony from Lorraine Minnite, a Rutgers University expert on voter fraud, who said such fraud was "exceedingly rare."
"I'm just not persuaded in the absence of evidence it exists," she said.
Before the trial began, the Pennsylvania Secretary of State said that more than 758,000 people, or 9 percent of Pennsylvania voters,. Matt Barreto, a political scientist from the University of Washington, testified that his analysis reveals that 1.3 million eligible Pennsylvania voters lack such ID.
Secretary of State Carol Aichele admitted during her testimony that she didn't really know exactly how the law worked or how many voters would be impacted.
Kurt Myers, deputy secretary of the Pennsylvania Transportation Department, said the agency has not increased staff or supplies to accommodate additional people seeking an ID. He also said many people are unable to complete the process because the lack the proper documents, according to a synopsis of his testimony provided to CBS News by the Advancement Project, one of the plaintiffs in the case.
"The information is just not getting out quick enough" to inform voters of the new requirements, John Jordon, director of civic engagement for the NAACP, said during the hearing. He said sufficient voter education was impossible before November.
Pennsylvania is one of ten states to
Critics of the lack of proven voter fraud in Pennsylvania pointed to statements by members of the Republican-led legislature to argue the law is tied to election-year politics.
Pa. Rep. Mike Turzai, House Majority Leader, said at one point that the law "is going to allow Governor Romney to win the state of Pennsylvania."
