The perils of paperless e-voting
ASK THIS | July 08, 2005

Let’s say your state or local election officials have a paperless
e-voting system or are thinking about switching to one. Here are some
questions you should ask to see if they’ve really thought it through.

By David Dill
Q. There has been a lot of controversy about electronic voting in the
last few years. In particular, it seems that many experts in computer
technology have grave concerns about the trustworthiness of paperless
electronic voting. Have you sought advice from computer experts? Have
you spoken with experts opposed to paperless systems? (The answer is
almost certainly "no", but if it is "yes", who were they, and why did
you not find those arguments convincing?)
Q. There have been several cases in the last few years where paperless
systems have irretrievably lost votes. Suppose that the vote totals
reported by the machines seem suspicious. How are you going to do a
recount? (If the answer is that they'll print the paper ballots from
memory and count them, the obvious follow up is: Why would this satisfy
a candidate? If the votes were not recorded properly, won't the paper
printouts have the same problems as the electronic records? That's not
the same as recounting ballots that the voter was able to check, is
Q. At this point, over 20 states have passed laws requiring voter
verified paper records, and there are several bills pending in the U.S.
Congress that would do the same. Aren't you bucking a trend here? What
will you do if a paper ballot requirement is imposed in the future?
Q. Unlike paperless systems, precinct-count optical scan systems call
for voters to fill out a ballot and put it in a scanner, which counts
the votes and stores the ballot in a secure manner. There is strong
evidence that such systems are not only much less expensive to acquire,
but less costly to maintain, than paperless systems.  For example,
Miami-Dade County recently proposed scrapping the paperless systems
they bought for over $20 million less than three years ago because of
the ongoing costs of maintaining those systems. Have you done a careful
cost comparison -- and, if so, would you release it? Why do you feel
that buying a paperless system is cost-effective?
Hundreds of computer technologists and thousands of others have
endorsed this resolution, which concludes that unauditable voting
equipment will erode confidence in our elections, causing further
disillusionment of the voting public.

Here are definitions for some key terms:
Paperless e-voting or Direct Recording Electronic voting machines
(DREs): Electronic voting machines that store an electronic ballot
internally.  The problem with these machines is that the machine can
show the voter a vote for candidate A but record a vote for candidate B
internally, without the voter detecting it. There is no way to do a
meaningful recount on these machines. The machine just echos the same
numbers it produced the first time, or, more expensively, prints paper
copies of the electronic ballots
stored internally.

Voter verified paper ballots (VVPB):  A paper ballot that the voter can
inspect before casting.  The votes on the paper ballots themselves are

Optical scan systems:  The ballot is like a standardized exam. The
voter fills in "bubbles" or inks in a gap in an arrow. The ballots are
counted by machine, either in the central office or at the precinct.

Precinct Count Optical scan: An optical scan system where the ballot
scanner is in the precinct.  The voter or someone else puts the ballot
in the scanner, which counts the votes and stores the ballot in a
secure manner.  If so configured, the machines can reject the ballot if
it can't be read properly.  Precinct count systems have been studied
extensively by political scientists, who have found them to be much
less conducive to voter error than punch cards.  In this respect they
are competitive (perhaps better) than DREs.  Precinct count optical
scan systems are very widely used in the United States.

Voter verified paper records (or audit trails): A paper record of the
vote that the voter can inspect before casting. Votes can be stored and
counted electronically, but the paper records are available for manual
audits or recounts.
