As debate rages on Tennessee's voter ID law, the Pew Center on the States has found that 24 million voter registrations in the United States have serious errors. All told, one in eight registrations is flawed in some way, including almost 2 million dead people who are still on voter rolls.
Inaccurate registrations -- especially among the dead -- can be fertile soil for fraudulent voters to claim a different person's identity and vote in that person's name. We can prevent that with a simple requirement of valid photo ID at the ballot box -- as Tennessee law now provides.
That's a requirement worth preserving.
