(Harrisburg) -- Groups opposed to a state House voter ID proposal say it wouldn’t address fraud as much as some supporters say. The bill would require people to show state-issued photo ID before they vote. Its sponsor, Representative Daryl Metcalfe, talks about his measure weeding out fraud that happens when people register to vote. Karen Buck, who runs the SeniorLAW Center in Philadelphia, says one has nothing to do with the other. "Voter registration and voter impersonation at the polls, the fraud is very different and distinct. And the only type of voter fraud that this unnecessary legislation would prevent is someone going to the polls and pretending they are you. And that type of impersonation is very rare," Buck says. Metcalfe says photo ID is necessary for so much these days, it only makes sense to make it a prerequisite for voting. Opponents say the requirement isn’t so easily met by people without driver’s licenses or those unable to produce other forms of photo ID. The groups represented Pennsylvania seniors, blacks, and people with disabilities.
