Check out this great USA Today article about the Diebold e-voting machines that have caused so much controversy. It’s a little surprising to see something like that mentioned in mass media, and I like seeing it there. Hopefully more will be done on the pitfalls of these systems before the election.
For the record, some SC counties use the Election Systems & Software iVotronic system. You can read more about it here. While the iVotronic has not come under the same scrutiny that the Diebold system has, there are still some concerns over it, as this thread at Black Box Voting will attest. Some good stuff there, and worth looking into.
