UPDATE: In her testimony, Pennsylvania Secretary of State Carol Aichele conceded,"I don’t know what the law says," and could not support her claim that 99 percent of voters have an acceptable ID, while plaintiffs demonstrated that they have not been able to get it. Closing arguments were heard this morning. A ruling should come in the next few weeks. Mayor Michael Nutter of Philadelphia – where up to 43 percent of voters may lack valid ID – has harshly criticized the law, calling it "a bad solution looking for a problem."

Earlier this year, Pennsylvania lawmakers passed HB 934, a voter ID law whose original sponsor, Daryl Metcalfe, is an ALEC member. Voting rights advocates filed a lawsuit in May, and in June, Allegheny County Executive Rich Fitzgerald announced that he, too, plans to challenge the law in court. Fitzgerald and local officials cite the legislation as being too expensive and too difficult to implement by November, among other major flaws.
