This Wired story makes a pretty good case that some of the new-fangled voting machines in California will open today's election up to any number of legal challenges.
Alameda County uses 4,000 touch-screen voting machines manufactured by Diebold Election Systems. But last month, officials in Maryland released a report saying that the Diebold machines were "at high risk of compromise" due to security flaws in the software. Despite this, officials in Alameda County said their policies and procedures for using the machines will secure them against voting fraud.
However, information obtained by Wired News at a training session for Alameda County poll workers indicates that security lapses in the use of the equipment and poor worker training could expose the election to serious tampering.
