NEWS RELEASE, September 24, 2002
Rebecca Mercuri rebuts recent MIT/CalTech voting systems analysis and calls
for moratorium on new electronic balloting equipment purchases
After reviewing the press release issued September 19 by MIT and CalTech,
electronic voting system expert Rebecca Mercuri revealed that "the conclusion
that MIT/CalTech researchers has drawn, that Florida's new voting technology
shows a 35% improvement, is based on a flawed analysis and is likely erroneous."
She goes on to state that not only are the researchers comparing "apples
to oranges" in terms of the types of technologies surveyed (punch-cards
versus optically scanned and DRE machines), but they have misleadingly
compared Gubernatorial general election results to Gubernatorial primary
results (and only for the Democrats in the 2002 primary).
It is well known that voters in general elections turn out in far greater
numbers (in Florida it is estimated that the November election will show
a 400% increase or more) than in primaries, putting greater strain on the
performance of systems as well as on poll workers and voters. The
balloting style of the typical primary voter (usually a party insider,
and certainly a partisan with a larger interest in selecting candidates
for each race on the ballot) is quite different from the general election
voter, where independents and other non-declared or minority party affiliation
citizens are permitted to cast ballots. Thus, only in November will
we be able to ascertain whether the residual vote rate has actually "improved."
Hence, Dr. Mercuri asserts, "the conclusion is premature, as well as flawed."
Laudatory statements made by Stephen Ansolabehere, Charles Stuart and R.
Michael Alvarez regarding Florida's new voting systems are also sorely
misleading, and do not support their conclusion of 35% improvement.
MIT Professor Stuart's comment that "most of the problems covered by journalists...did
not concern equipment malfunctions" is not based on an analysis of the
numerous and severe voting system problems that occurred throughout the
state, but rather on the media reports that surfaced. Many equipment
malfunctions were reported by the Associated Press and other news bureaus,
but these were obfuscated by the public interest stories that alternatively
showed voters "pleased with the new equipment" or being "turned away from
the polls in droves."
A lot of the media attention focused on press comments by Governor Jeb
Bush and members of his staff who erroneously characterized the problems
as being based only in two counties (Miami-Dade and Broward) and blamed
the poll workers and election officials there for the situation.
In actuality, Miami-Dade and Broward could not have purchased the ES&S
machines had they not been pre-certified by the state for use. Sadly,
this certification failed to provide the counties or their poll workers
with sufficient notification as to the fact that the voting machines would
take 10 minutes to start up, with the ones outfitted for the visually impaired
taking an astonishing 23 minutes. Some machines also contained a
"safety feature" that did not permit them to be turned on before 6AM on
election day. Since each unit is activated sequentially, simple math
shows that a polling place containing 10 voting machines, with one outfitted
for the visually impaired, would not be fully operational until nearly
8AM (an hour after the polls opened) under the best conditions. Mercuri
states: "I certainly do not see how this can be blamed on the poll-workers,
nor how it constitutes an improvement. I'm hard pressed to think
of any computer equipment manufactured after the 1970's that takes 23 minutes
to be started, especially those deployed for use entirely in time-critical
operations. The failure by MIT/CalTech to raise serious concerns
about the engineering of these products is remiss."
MIT's Ansolabehere stated that "the machines used showed clear gains over
the technologies used in past elections." To which Dr. Mercuri replies:
"Yes perhaps, if one considers declaring a state of emergency (under threat
of lawsuit by a major candidate) and extending the election day by two
hours a "clear gain." How about in Union County, Florida, where 2,700
optically scanned ballots had to be hand counted, because the computers
were erroneously programmed to only tally votes for Republican candidates?
At least there, the ballots could be recounted because they were on paper.
What about the precinct in southern Florida that showed a 1200% voter turnout
(12 times as many voters as were registered) because the DRE activation
cards permitted voters to cast ballots on machines in the same building
that were not in their precinct? And what about some precincts in
Miami-Dade and Broward where the vote cartridges reflected over 40% residual
votes (lost or missing) and data had to be "extracted" from back-up memory
inside of the machines (one wonders how trusted the reconstructed results
CalTech's Alvarez states "we are learning important lessons about how to
make such important changes in voting technologies" and Mercuri asks: "Is
it fair to allow Florida and other states and communities to feel pressured
to replace their voting systems while being treated as guinea pigs?
Is the United States prepared to reimburse communities for defective and
obsolete equipment once new standards are in place (since all election
equipment is still being inspected by the National Association of State
Election Directors testing authorities to the outdated 1990 Federal Election
Commission guidelines)? Is it acceptable to certify voting equipment that
can be reprogrammed internally via a portal on the device (as some were,
only weeks before the election in Palm Beach County as well as elsewhere
in the state)? These new technologies are playing a role in electing
government officials - the confidence citizens have in the democratic process
is at stake."
Mercuri, who has testified before the U.S. House Science Committee regarding
the need for involvement of the National Institute of Standards and Technologies
in establishing criteria for the procurement and testing of election equipment,
feels that congressional election reform is sorely needed. But, she notes
that many of the laws proposed at federal and state levels, or enacted
since 2000, have been weakly worded so as to permit the production of election
equipment that does not provide an independent means whereby voters can
verify human-readable ballots that are secured and available for recounts.
"Real election reform," Mercuri says, "is only possible within a context
of adequate and enforceable standards for construction, testing, and deployment
of voting equipment."
But Mercuri worries that the trend to full automation of the voting process
could be used to conceal election fraud. She warns, "It is entirely possible
that Florida and other states may smooth out their election day problems
such that it appears that the voting systems are functioning properly,
but votes could still be shifted or lost in small percentages, enough to
affect the outcome of an election, within the self-auditing machines.
Whether this occurs maliciously or accidentally, it presents a frightening
prospect. Thankfully, new products are being developed that provide
the voter with a way to determine that their ballot has been tabulated
correctly, without revealing the contents of their vote, but deployment
of such systems is a few years down the road."
For these reasons, Dr. Mercuri has requested a moratorium on the purchase
of any new voting systems that do not provide, at minimum, a voter-verified,
hand-recountable, physical (paper) ballot while appropriate laws, standards,
and technologies are developed that will provide accurate, secure, reliable,
and auditable voting systems. She urges MIT, CalTech, and other concerned
scientists, public officials and private citizens to join her in this cause.
