"Electronic voting" refers to two methods of collecting information from the voter -- "optical scan" systems, in which the voter fills out a paper ballot that is then scanned by a computer, and "touch screen" systems, in which the vote is cast directly on the machine. The following concerns have been raised about both methods:
It seems to me that the voting machines that rely on computer based counting of votes are inherently faulty in that there is no fool safe way to insure fair elections. The counts are all on computers and it is computers that do the re-count. With no paper trail, it is impossible to guarantee all votes will be counted.
solution: do away with computer based voting machines and return to paper. I believe either Minnesota or Wisconsin has this and are very happy with it.
