The SEIU said hundreds of thousands of Ohioans may be without photo identification to use at the polls in conformity with the new voter ID law.  There's one little problem, the data don't agree.  Columbus Dispatch:

"But records from the state Bureau of Motor Vehicles show about 8.83 million voting-age residents have an Ohio driver's license or photo ID - about 28,000 more than there are voting-age residents in the state, according to the 2010 census."

Of course the opponents of voter ID argue that some people have multiple driver's licenses or might have moved away.  But they don't have any social science data to back up that assertion, yet.
