Computer security experts have warned for years that some voting machines are vulnerable to attack. And this week, in Virginia, the state Board of Elections decided to impose an immediate ban on touchscreen voting machines used in 20 percent of the state's precincts, because of newly discovered security concerns. The problems emerged on Election Day last November in Spotsylvania County. The AVS WINVote touchscreen machines used in precinct 302 began to shut down. "One machine would go and crash. They'd bring it back up. Another one would crash," said Edgardo Cortes, the state's elections commissioner. "Starting in the early afternoon, they brought in a piece of replacement equipment that experienced the same issues when they set it up in the precinct."
