This article discusses hacking in relation to the U.S. democratic process. I found it rather interesting that educated security personnel had a few comments on the subject. "It might be possible to change some votes, but to change the outcome of an election and do so in a way that could not be detected is not practical at this point." Apparently the current system(s) used by each state makes it rather difficult to influence the elections in any major or undetectable manner. The question is raised if suggested systems by the media recently are actually safer and what would be realistically required for a standardized IT solution to voting.
