A federal trial scheduled to begin Monday in Wisconsin could set the stage for legal challenges in a number of states to laws requiring voters to show photo identification at the polls.
Wisconsin's photo voter ID law has been on hold since Dane County judge declared it unconstitutional soon after it passed in 2011.
Supporters say the law helps combat voter fraud. Opponents say it disenfranchises poor and minority voters who are less likely to have state-issued identification.
The trial involves a federal lawsuit filed on behalf of a now-deceased Wisconsin woman who was born at home in Jackson, Tenn., in 1935 and never received a birth certificate. Her daughter says that without a birth certificate, Bettye Jones had to fight for months to get a state ID to vote.
