The Startling Urban Dynamic in Pennsylvania's Voter ID Law

Something big is happening in Philadelphia ahead of this fall’s presidential election – the first in the state since a stringent new Voter ID law was passed earlier this year – although people there concerned about it are having a maddeningly hard time putting their finger on the precise size of the problem. The city has just over 1 million registered voters. About 800,000 of them are considered "active."

"And about a third of them are on one of these two lists as potentially having ID problems," says Tom Boyer. He's a former journalist and computer scientist living in Philadelphia who has gotten involved in analyzing the potential impacts of Pennsylvania’s controversial law, which is now in the throes of a legal challenge. Boyer suspects that something historically bad could happen if the law isn’t overturned, and not enough people are talking about it.
