South Dakota has a great compromise when it comes to electronic voting.
The ballots are the standard fill-in-the-circle sheets that everyone used in school. You slide the ballot into the evoting station and it comes up with the ballot questions. You make your choices on the touch screen (it also has headphones you can use if you are blind). After all the questions are done, it shows you your choices and you can make changes. Then it marks your ballot for you and spits it back out so that you can review it for yourself. After that, you slide it into the lock box and it is tabulated using a scantron machine.
One big benefit to this is that if there are problems with the voting machines, you can still fill it out with a pen. You also have a physical ballot that can be recounted.
Anyone that has a miss-vote in South Dakota deserves to have their ballot thrown out. There are too many safeguards in place.
There is another good reason to stay away from political stories like this. A writer will always miss important information. Like this quote.
"But at the news conference with Nickolaus, Ramona Kitzinger, the Democrat on the Waukesha County Board of Canvassers, said: "We went over everything and made sure all the numbers jibed up and they did. Those numbers jibed up, and we're satisfied they're correct."" http://www.jsonline.com/news/statepolitics/119410124.html
