Pretty much everyone, it turns out. According to a Pew Center study, about 24 million voter registrations in America have a "serious problem" with them. 1.8 million dead people are registered. A whole lot more (2.7 million) have active registrations to vote in more than one State. Over 12 million have addresses listed that are so incorrect that mail would not be delivered if sent to them at the registration address. Many have more than one defect. But don't worry, the fact that one out of every eight voter registrations in America have what is termed a "serious problem" is not indicative of wide spread voter fraud, according to Pew. It just means we should update our system. Yeah, OK. Here is one simple and cheap update: make everyone show a valid ID when they show up to vote. Problem solved.
