In my previous article, I discussed 10 ways that voting machines could cheat, in ballot-marking, ballot-scanning, and ballot tabulating; and I discussed which of these cheats could be caught and corrected during risk-limiting audits and recounts of the paper ballots.  In particular, cheat-methods 1, 2, 5, and 7 will be detected/corrected by audits/recounts; methods 3,4,6,8,9,10 […]

Summary:  Voting machines can be hacked; risk-limiting audits of paper ballots can detect incorrect outcomes, whether from hacked voting machines or programming inaccuracies; recounts of paper ballots can correct those outcomes; but some methods for producing paper ballots are more auditable and recountable than others. A now-standard principle of computer-counted public elections is, use a voter-verified […]

In my last three articles I described the ES&S ExpressVote, the Dominion ImageCast Evolution, and the Dominion ImageCast X (in its DRE+VVPAT configuration).  There’s something they all have in common: they all violate a certain principle of voter verifiability. Any voting machine whose physical hardware can print votes onto the ballot after the last time […]

States and counties should not adopt DRE+VVPAT voting machines such as the Dominion ImageCast X and the ES&S ExpressVote.  Here’s why. Touchscreen voting machines (direct-recording electronic, DRE) cannot be trusted to count votes, because (like any voting computer) a hacker may have installed fraudulent software that steals votes from one candidate and gives them to […]

The Dominion ImageCast Evolution looks like a pretty good voting machine, but it has a serious design flaw: after you mark your ballot, after you review your ballot, the voting machine can print more votes on it!.  Fortunately, this design flaw has been patented by a rival company, ES&S, which sued to prevent Dominion from selling […]
