A previous dispatch noted the great elections data available from Cuyahoga County, Ohio.
Among those data is information about differences between the number of signatures in the poll books and the number of ballots cast, which at the end of Election Day should be the same. During the March 2012 primary, these numbers matched in approximately 83 percent of the county’s more than 1,000 precincts. They did not match in 177 precincts. In nearly three-quarters of the precincts there was a difference of one. In one precinct there was a difference of six.
