Guess I was off by 10,000, if the Philadelphia Inquirer is right.State figures also can be hard to nail down. In Pennsylvania, nearly 760,000 registered voters, or 9.2 percent of the state's 8.2 million voter base, don't own state-issued ID cards, according to an analysis of state records by the Philadelphia Inquirer.
