In response to the story written by Paul Festa, "":
All the serious technical people are convinced that there must be a paper audit trail for a voting machine--a piece of paper the voter will see and read. Rebecca Mercouri, professor of computer science at Bryn Mawr College, and others go further, suggesting that that piece of paper be the legal ballot.
At that point, it is simpler, more direct and much more confidence-inspiring to have the voter mark that ballot directly with a felt marker as is done now without the intervention of a computerized (and hackable) "voting machine."
The voting machine serves no useful purpose except to increase its manufacturer's profit. People who believe in possible conspiracies will say it's also designed to open a door to hacking the vote. It's a classic case of fixing what ain't broke.
