HARRISBURG -- A statistics expert hired by opponents challenging Pennsylvania's voter ID law testified this morning that hundreds of thousands of registered voters do not have valid identification issued by the state Department of Transportation.
Bernard Siskin, a former chairman of the Temple University statistics department and now at a private firm, described how he matched registered voters to people who have a driver's license or other identification issued by PennDOT.
His analysis found that more than 500,000 registered voters either appeared to never have obtained such an ID or had an expired ID that would not be acceptable at the November 2013 election.
An attorney for the law's challengers questioned Mr. Siskin about criticisms of his work made by an expert hired by the state.
That statistician estimated the numbers of voters who would be eligible for other forms of identification acceptable under the law, such as IDs issued by universities or nursing homes.
The estimates of people ineligible to vote or eligible for other identification came to more than 140,000.
There was no cross-examination before a lunchtime break. But opening arguments Monday suggested the state would not argue that all registered voters have acceptable identification, but rather that such identification is readily available.
The requirement that voters show photo identification at the polls was suspended for the November 2012 election and the May primaries this year.
Opponents are now in the second day of a hearing on their attempt to permanently block the law.
