Avi Rubin, a critic of Diebold's electronic voting machines, tells the story of his day as an election judge on super Tuesday, noting lapses in security and also the public's very positive response to these machines. Very frightening reading, but also believable for anyone who has ever been a poll worker. I found the piece via MIT's Technology Review newsletter.
I'm reminded of my own experience as an election judge last May. We used mechanical voting machines, which marked the tallies on large sheets of paper. I found the process reassuring. I liked being able to see and hear the count, and know that I was a witness. I worry about a closely contested election in a situation where there is less concrete accountability.
