Editorials: A simple step every state could take to safeguard elections | The Washington Post
Election security is a complex challenge. One essential step, however, is so simple it can be carried out with a pen and paper. Pennsylvania officials have announced that Philadelphia and Mercer County will conduct a post-election pilot next month of what’s called a risk-limiting audit. The procedure is new to most of the country, but 12 states are experimenting with it — because it’s that much of a no-brainer. Currently, 17 states are not required by law to verify the accuracy of their vote tallies at all. Those that are mostly do so the “traditional” way, which in this case means the wrong way. The process auditors typically use — manually recounting votes in a predetermined percentage of precincts — tells officials whether a particular machine or group of machines is working, but it doesn’t actually answer the essential question: Did the declared winner actually win? Risk-limiting audits instead do what any mathematician . They hand-count a statistically meaningful sample of all votes to determine whether the original tally was correct. The required sample increases as the margin of victory narrows. It’s easy, and it’s time-consuming only in the tightest elections, or when something actually has been tampered with. Of course, that’s when it’s most worth investing the time. So why isn’t everyone doing it?
