Except this article is talking about online voting which means:
1) Any computer connected to the Internet can vote in the election. This includes grandma's unpatched Windows XP box with the 50 browser toolbars that she opens all those e-mail attachments with.
2) There is no verification of identity. Is "John Smith" who is voting really "John Smith"? Or did some hackers steal his voting credentials? Or maybe John's employer demanded his voting credentials to ensure that John votes "the right way."
3) Speaking of John's employer, John might be really casting the vote (and thus would pass identity verification), but might be doing it from his work computer with his employer looking over his shoulder to ensure the "correct" vote is cast. Anything "incorrect" and John will find himself out of work. (In case John sues, the company lawyers are standing by to drag the case on until John goes bankrupt and drag John's name through the mud so much that he will never find work again.)
I agree with other people that Election Day should be a national holiday. We should have the day off (or, at least, a half day off) so that everyone has time to make it to the polls. Being able to go to a physical polling location would negate any need for online voting.
