A House subcommittee is expected to vote this week on a bill that would direct a federal lab and state and local election officials to set new standards for voting equipment.

But a new report from researchers at Cal Tech and MIT has concluded that faulty equipment is only the tip of the iceberg. The new report finds that as many as 6 million people nationwide were disenfranchised by confusing ballots, faulty equipment, inadequate voter registration and understaffed polling places in last year’s election.

While much attention has focused on Florida, where Republicans urged officials to ignore state election laws, the MIT/Cal Tech study finds that other states were worse than Florida when it came to disenfranchising voters.
