Unfortunately, most of the links I have on this topic are either reactionary, inflammatory, or both, and you have to do some research to get to the actual information. Regardless, I'm dropping a post in here because in spite of all that, the implications are beyond scary.
In short, many counties, states, etc. are switching over to electronic voting systems for their next elections. This is mostly, of course, because of the Floridians. The reasons why are now irrelevant however. What we're left with is the bitter truth: That software corporations will hold our votes in their little error-prone hands.
The name most commonly mentioned in stories about this stuff is Diebold. Their security problems have been in the news lately because of buggy software and an unforgivable lapse in security: They left a huge collection of files (40,000 or so) from some internal server wide open to access from the internet. As a result, people have been poking through their programs and finding actual voting records from California. The potential for voting fraud in this system is pretty large. You may say there is a similar risk of fraud in the existing system, but the main difference lies in how much easier it is to hide your tracks when you mess with the records electronically. Since voting systems must be built with anonymity as a top priority, it makes data-alteration virtually undetectable.
So, with that in mind, here are some of the inflammatory links. First, a story that appeared today on Slashdot. Second, the article/commentary that's referenced in the Slashdot story. This commentary shows some signs of technical weakness which I'll try and summarize, but in general it's rather scary.
At one point, the author mentions how any system with a modem that can send information out is therefore open to have information sent in via that same connection. While this is potentially true, this has been a known issue for decades. Computers are commonly configured such that data may be sent out, but not allowed to come in, or vice versa. Unfortunately, computers also commonly have security holes in that system which allow people to circumvent the protections. For example: Microsoft. In this case, people are scared because Diebold in particular has already demonstrated that they're unable to keep their own asses from hanging out in the breeze, as it were.
So, to borrow a phrase my supervisor is fond of using... Electronic Voting: Threat or Menace?
