After more than a year on hold, a law that would require voters to show a state-issued photo identification card before casting ballots heads to court on Monday. At question is whether the 2012 law, which was blocked before the presidential primary, violates the state's constitution.

According to opponents of the law, if enforced it would disenfranchise racial and ethnic minorities, as well as students, low-income voters and non-English speakers.

During the trial, expected to last about two weeks, they will also argue that Pennsylvania has not made the ID cards "easily available," limiting the hours, days and sites where they can be obtained.

"Pennsylvania's photo ID law disproportionately burdens the commonwealth's most vulnerable voters, who are most likely to lack the required ID and more likely to have trouble getting it," said Penda D. Hair, co-director of the Advancement Project.
