The WaPo Reports:

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.

This is the work of a state employee who's tasked with maintaining ballot security. He's showing that vote-hacking is emminantly possible. Maybe if enough of these sorts of stories get out, election officials will fix their systems before this fall's balloting. However, I still think the threat of a widespread "hack the vote" activist effort would spur them to get their rears in gear.
