[EL] PA Sec of Commonwealth study on ID ownership

[Doug Hess]

This quote comes from this press release by the Pennsylvania Secretary
of Commonwealth found at

"A Department of State analysis shows 99 percent of eligible voters
already have an acceptable photo ID, and providing free photo IDs to
every other eligible voter, should they all request one, would cost
just over $1 million."

Has anybody seen this report? What level of "acceptable" did they use?
 According to NCSL, PA doesn't have such a requirement so what state
law are they using to decide that 99 percent of residents have one?
Here's the NCSL mape on voter ID laws http://www.ncsl.org/?tabid=16602
