Twenty-seven states have passed legislation that, at least, requires that voting machines allow the voter to see her choices on paper. Iowa remains among a minority of states that still allows paperless voting. It's time to change that. Iowans for Voting Integrity has developed a petition to the 82nd General Assembly calling for verified voting. Our list of essentials includes: going beyond a "paper trail" for voting machines and back to paper ballots, hand audits of ballots in randomly selected precincts, stronger chain of custody procedures for ballots and election records, and disclosure of voting system software.
