The basic idea behind a paper trail is that you take one of these electronic systems and you augment it with a printer that prints out people's vote as they vote.

Many of the touted advantages of electronic voting can still be achieved with paper ballots if you use a computerized ballot marking scheme.

I think that, you know, looking at all the systems that I've been studying over the last several years, that paper ballots with a precinct optical scan counters and random audits is the best system that we can have.

My position hasn't changed over the years. Which is that online voting is a very unsafe idea and a very bad idea and something I think no technological breakthrough I can foresee can ever change.

People's computers are not getting more secure. They're getting more infected with viruses. They're getting more under the control of malware.

Hacking a national election is simple. Exploit a vulnerability in the manufacturer's network, poison the tabulation software update with self-deleting malware and let the manufacturer send to their field reps and election consultants who update the election systems.
