Sister Julie McGuire said she was forced to turn away her fellow sisters at Saint Mary's Convent in South Bend, across the street from the University of Notre Dame, because they had been told earlier that they would need such an ID to vote.
The nuns, all in their 80s or 90s, didn't get one but came to the precinct anyway.
"One came down this morning, and she was 98, and she said, 'I don't want to go do that,"' Sister McGuire said. Some showed up with outdated passports. None of them drives.
They weren't given provisional ballots because it would be impossible to get them to a motor vehicle branch and back in the 10-day time frame allotted by the law, Sister McGuire said. "You have to remember that some of these ladies don't walk well. They're in wheelchairs or on walkers or electric carts."
Nonetheless, she said, the convent will make a "very concerted effort" to get proper identification for the nuns in time for the general election. "We're going to take from now until November to get them out and get this done. You can't do this like school kids on a bus," she said. "I wish we could."
Elsewhere across the pivotal state, voting appeared to run smoothly, despite the fears of election experts that the Supreme Court's recent refusal to strike down Indian's controversial photo identification law could cause confusion at the polls.
A voter hot line set up by the secretary of state's office had no complaints regarding photo IDs as of 3 p.m., said spokeswoman Bethany Derringer. In a primary expected to draw record numbers, most calls concerned precinct locations.
"The No. 1 call they've heard so far is just people asking where they can go to vote," Derringer said.
But a group of voting rights advocates that established a separate hot line reported receiving several calls from would-be voters who were turned away at precincts because they did not have a state or federal identification bearing a photograph.
One newly married woman said she was told she couldn't vote because her driver's license name didn't match the one on her voter registration record, said Myrna Perez of the Brennan Center Justice at New York University's law school, coordinator of the 1-866-OUR-VOTE hot line. Another woman said she was turned away from casting her first-ever ballot because she had only a college-issued ID card and an out-of-state driver's license, Perez said.
"These laws are confusing. People don't know how they're supposed to be applied," she said.
Indiana's photo ID law is the strictest in the country. The Republican-led effort was designed to combat ballot fraud, said supporters, who also have acknowledged that no case involving someone impersonating a voter at the polls has ever been prosecuted in Indiana.
The state's American Civil Liberties Union sued, calling the law a poll tax that disproportionately affected minorities and elderly voters, those most likely to lack such identification. On April 28, the Supreme Court ruled 6 to 3 that the law did not violate the Constitution.
Since then, advocacy groups have fretted that people showing up to vote in Tuesday's primary would not understand their rights under the law, which include being able to cast a provisional ballot and obtain a proper ID within 10 days so that ballot would be counted later.
Rick Rice, a precinct judge at the Charles Martin Youth Center in South Bend, said one person complained about the voter ID law when he attempted to use a federal identification that didn't have an expiration date on it.
"I didn't know who it was put out by, but we couldn't accept it," Rice said. "He had a driver's license, he was just trying to make a point. He wanted to push it and the law is very clear."
Rice said the man voted, then asked where he could write to file a complaint.
Sean Greene, of the nonpartisan electionline.org, was monitoring precincts in the Lafayette area of Tippecanoe County. "It's going pretty well," he said, despite long lines. "Most of the people I've seen today are prepared and used to this. They have their IDs out already.
That thought was echoed in South Bend, where Elizabeth Bridges, 63, said half of the people working in her voting precinct were family members, but still she showed her ID.
"I think the law is a good thing because a lot of people are crooked," she said.
John Parker III, agreed.
"I think it's a good thing because I don't want anyone coming in and voting for me," he said. "Someone could come in here and just use my name."
