In Controlled Test, Results Are Manipulated in Florida System

As the Leon County supervisor of elections, Ion Sancho's job is to make sure voting is free of fraud. But the most brazen effort lately to manipulate election results in this Florida locality was carried out by Sancho himself.

Four times over the past year Sancho told computer specialists to break in to his voting system. And on all four occasions they did, changing results with what the specialists described as relatively unsophisticated hacking techniques. To Sancho, the results showed the vulnerability of voting equipment manufactured by Ohio-based Diebold Election Systems, which is used by Leon County and many other jurisdictions around the country.
