Common Cause, the Verified Voting Foundation, and the Rutgers School of Law have a new report out on the readiness of particular states for the election in November. The report focuses on the nuts and bolts of voting: do states have back-up methods in case voting machines break? Do they keep paper records of all votes? Do they conduct audits after the election to make sure the count is correct? It doesn't touch on more contentious issues like voter ID or the ability of released prisoners and other felons to vote.
Minnesota, New Hampshire, Vermont, Wisconsin and, interestingly, Ohio were judged the five best prepared states, and Colorado, Delaware, Kansas, Louisiana, Mississippi, and South Carolina the least prepared:
The report found no states had inadequate measures for dealing with broken voting machines, but that sixteen use paperless voting without any paper receipts, meaning that a verifiable vote audit is impossible. You can read the full report here (pdf).
