On Thursday, the Pennsylvania Supreme Court is scheduled to hear arguments about the state’s strict new photo ID law, which is allegedly intended to prevent voter fraud. A voter must present a government-issued or other approved photo ID at a polling place to vote or can file a provisional ballot, which must be validated later by a submission of a photo ID or proof that the voter is indigent. The state has offered no evidence of voter identity fraud to justify this law. There is no legitimate government interest that justifies the burden the law imposes on voters. If the court does not block the law, it will cause irreparable harm. In Philadelphia, for instance, almost one-fifth of the registered voters may not have an acceptable form of identification to vote on Election Day. Statewide, almost one-tenth may not. When he signed the law in March, Gov. Tom Corbett claimed that it “sets a simple and clear standard to protect the integrity of our elections.” But, at a meeting of the Republican State Committee in June, the House majority leader, Mike Turzai, boasted that it would “allow Governor Romney to win the State of Pennsylvania.”
