eldavojohn writes "You may be able to argue that a five-thousand-vote error is a small price to pay for a national election, but these errors are certainly inadmissible on a much smaller scale. According to the Rapid City Journal, a software glitch added 4,875 phantom ballots in a South Dakota election for a seat on the city council. It's not a hardware security problem this time; it's a software glitch. Although not unheard of in electronic voting, this bug was about to cause a runoff vote since the incumbent did not hold a high enough percentage of the vote. That is no longer the case after the numbers were corrected. Wired notes it's probably a complex bug as it is not just multiplying the vote count by two. Here's to hoping that AutoMark follows suit and releases the source code for others to scrutinize."
