Spurred by the disclosure that 758,000 registered voters do not have Pennsylvania drivers' licenses, six civic groups called on Gov. Corbett Friday to delay implementation of a new voter ID requirement for at least a year.

The Corbett administration immediately rejected the request.

"Our goal since the law was signed is to reach out to all voters to make them aware of the law so all eligible voters are able to get ID if needed, and cast ballots in November," said Ron Ruman, a spokesman for the Pennsylvania Department of State, in charge of the state election machinery.

Ruman said Corbett did not have authority on his own to delay the photo ID requirement, and would not ask the Republican-controlled legislature to change the law, passed and signed by the governor last March.

"The administration supports the law," Ruman said in an email, "because it protects the integrity of every vote and voter by giving Pennsylvania for the first time a reliable way to verify the identity of each voter at the polls. This will help detect and deter any illegal voting."

The new law will require every voter going to the polls in November to provide a specified form of photo identification: either a Pennsylvania driver's license, a non-driver photo ID issued by PennDOT, a U.S. passport, a photo ID from an accredited Pennsylvania college, U.S. military ID, ID from a Pennsylvania care facility, or photo ID issued to government employees.

While PennDOT ID would be valid for voting purposes up to 12 months after expiration, the other forms of ID would have to be current, with specified expiration dates.

When the photo ID requirement was moving through the legislature last winter, Secretary of the Commonwealth Carol Aichele advised lawmakers that 99 percent of the state's voters already had the necessary identification, most of them through PennDOT.

Tuesday afternoon, the day before the July 4th holiday, her department issued a press release disclosing the results of a computerized match between PennDOT's databases and a database of registered voters.

It showed 758,000 voters statewide – about 9.2 percent – did not have PennDOT-issued ID, either a driver's license or a non-driver photo ID.

In Philadelphia, the numbers were significantly worse, with 18 percent of registered voters not having PennDOT ID.

Six organizations, including the state League of Women Voters, Pennsylvania Common Cause, the state ACLU, the Philadelphia AFL-CIO, the Committee of Seventy and The Advancement Project, cited the numbers Friday while asking the state to postpone voter ID.

"We are urging Gov. Corbett to go to the leaders of the General Assembly with a bill to delay implementation of the voter ID law for at least one year, so all the state's 8.2 million voters can be properly educated . . . and people who do not have a photo ID for voting can have ample time to obtain one," said Ellen Mattleman Kaplan, vice president and policy director for the Committee of Seventy.

The ACLU and the Advancement Project are both providing legal support trying to have the law ruled a violation of the state Constitution. A Commonwealth Court hearing is scheduled for July 25.

The Pennsylvania Voter ID coalition, roughly 100 groups concerned about the impact of the new law, is offering advice and help on compliance. Its telephone hotline is 1-866-OUR-VOTE (1-866-687-8683).
