Chicago on-line voter registration list hacked

A group claims they've hacked into the on-line Chicago voter registration data base and could have disenfranchised every Chicago voter:

Oct. 23, 2006 — As if there weren't enough concerns about the integrity of the vote, a non-partisan civic organization today claimed it had hacked into the voter database for the 1.35 million voters in the city of Chicago.

... A nefarious hacker could have changed every voter's status from active to inactive, which would have prevented them from voting, he said.

"Or we could've changed the information on what precinct you were in or what polling place you were supposed to go to," he said. "So there were ways that we could potentially change the entire online data base and disenfranchise voters throughout the entire city of Chicago."
