I do not understand why paper ballot would be difficult to achieve, that is the easiest to do! I never voted in the US, but the system seems overly complex for such a simple exercice. Here in Canada, we have a paper ballot (http://www.elections.ca/vot/yth/stu/gui/images/dxsmp1-e.jpg http://www.elections.ca/vot/yth/stu/gui/images/dxsmp1-e.jpg), which is pretty simple. The vote is done, the stub is tallied and 2 people need to verify the vote before dropping it in a sealed box. When the polls close, the votes are counted, by multiple persons, by hand. Nothing electronic. ... and there is a single vote at a time, no votes on laws when electing representative, etc. That is just non sense.
