Mitofsky on Mexico’s Standoff
Pew Research Center July 6, 2006
In an exclusive interview, Warren Mitofsky, creator of the exit poll
in 1967 at CBS News and now president of Mitofsky International,
explains why and how his firm’s exit poll in this week’s Mexican
presidential election accurately mirrored the closeness of the vote,
who the final winner will be, and why Mexico’s current electoral
system is superior to America’s in several ways.
Interviewer: Andrew Kohut, President, Pew Research Center
Q Tell us a little about Mitofsky International’s experience
conducting exit polls of the presidential elections in Mexico. Who is
your sponsor there? How many interviews did you do?
This is the third presidential election in which we did national exit
polls; we have done the mid-term elections in between. Our sponsor is
the television network Televisa. Normally they publish results on
election night — it’s pretty similar to what we do in the U.S.
This time we did about 35,000 interviews, maybe a little more — we
were in 520 precincts — we were doing four governor races so each
state became part of the national poll and half the precincts were in
those four states and the other half were in the rest of the county.
There are 32 states.
Q Did the results of the national exit polls mirror the close
division of the popular vote?
Absolutely. The exit poll results showed the two leading candidates
[Felipe Calderón and Andres Manuel López Obrador] running even. We
didn’t release the exact numbers from the exit poll; all we put on
the air was that it was too close to call. The reason for not putting
out the exact numbers was that we didn’t want to become part of the
dialogue of either of the candidates claiming they were ahead. Azteca
hasn’t put their numbers out either; they are the other large
television network.
Q What is the biggest difference between conducting an exit poll in
Mexico compared to doing one in the United States? And why do you
think this poll was so much more accurate than the exit polls for the
2004 presidential election?
There are a few important differences: One is that the response rate
is a lot better in Mexico. Also, we train the interviewers in person
rather than by telephone. Third is that when we do the research we
cannot get maps, which causes a problem. But we get good records,
good cooperation.
And we did one thing that hopefully I learned from the 2004 election:
We insisted in the personal training of the interviewers that they
absolutely stick to the sampling rate. And if there is a refusal they
continue the count to the next sample person; they don’t substitute
anyone in between.
Q So if I understand correctly, if I, the interviewer, am to talk to
every fifth person coming out the door and that person refuses, I
don’t go to the next person. Instead I go to the next fifth person
who comes out?
Right, there was no bias in this exit poll at all. In a typical
Mexican exit poll we overstate the PRI, which was the government
party that ran the country for the past 70 years, but which finished
third this time around. We usually overstate PRI and understate the
other two parties. This time the other two were understated by a
fraction of a percent and offset each other so there was essentially
no bias in the exit poll. I did the same thing in another exit poll
elsewhere and there was no bias there either.
Q Do you think Calderón’s current lead will hold up?
Right at the moment he is leading by just about the 200,000 votes I
expect him to win by.
Q That’s a thin margin, why do you think it will hold up?
Well look, there were two counts of the votes in Mexico. One is the
preliminary count, which they put out on election night; the other is
the real count, which has taken place over the past two days. In the
real count, 99.5% of precincts have been counted and they show the
same 200,000-vote lead they found in the preliminary count. And no
one challenged the preliminary count — no one said it was wrong –
so I expect the final count to mirror that.
Q Do you think the results of the exit poll will reduce chances of
fraud in the recount?
This election commission is so squeaky clean, I don’t anticipate
fraud. There were international observers there who said this
election was as clean as anything they had seen. The way the election
commission works, is that it represents all the parties — not just
the major ones — equally. They all have an equal voice, and they all
got to inspect every last count that took place, at every polling
place, at the 300 deputy districts where the votes were collected,
and again at the national level. I don’t see a whole lot of room for
fraud.
Q So you think there is less chance for fraud in a Mexican election
than in an American election?
I would think the Mexican system with its strong election commission
that is uniform across the country would be better than anything we
are doing in the U.S. One of the problems with the U.S. is we don’t
have uniformity from county to county and state to state. Every
county and state is making their own rules and they aren’t making
them consistently.
Let me mention one other thing: In this election there were
absolutely no leaks in the results from our exit polls by either
Telavisa or Azteca. The results were bottled up completely; they did
not get into the public dialogue. And the reason for that is we
didn’t circulate the results to anyone at Telavisa other than two
senior VPs of the place. We had no trouble keeping these results out
of the public dialogue.
Q Do you think you can do that in the 2008 presidential election in
the US?
Well if the networks want to let us control it of course we can do
that. But not if someone at the networks leaks it. If they don’t, it
will stay bottled up. They signal every intention that they will do
that, and I expect them to, but we have to see how it works out.
Q So I take it from this - that your view is that not only do the
Mexicans run better elections than the Americans, but that the
Mexican political class is more responsible than the American
political class?
I think they were very responsible in this election and certainly
more than the people who had access to the information in 2004. I
mean the leaking in this country is an abomination. They should all
know better.
Q What issues or candidate qualities were most important in
determining whether voters backed either Calderón or López Obrador?
It had to do with the constituencies, not so much the issues. López
Obrador’s constituencies were the poor, the intellectuals and a lot
of former supporters of the PRI. Calderón’s supporters were some PRI
supporters, but mostly the business community, the middle class and
the interests looking for more stability in the country.
Q Did Fox’s record help or hurt Calderón?
I don’t think it had much effect one way or the other.
Q If the PRI had not been in the election, if there wasn’t that third
candidate, where would those votes have gone?
Remember the PRI is a centrist party and got a lot of its strength
from the poor, the uneducated, the rural people. I would suspect
that’s the group that diminished over the years and I think that’s
why the PRI lost in the 2000 election. The PRI votes in the current
election probably would have gone more to López Obrador, that would
be my guess, but not by a lot. As a centrist party the PRI also had a
lot of business interests supporting it as well, except most of the
business interests left after the last election and went to Fox and
they stayed with Calderón. But this time I think López Obrador would
have picked up more if [PRI candidate] Robert Madrazo had not run.
Q Do you think the leftist sentiment we have seen in Bolivia and
Venezuela was a component of the support for López Obrador? Or do you
think that this Mexican election didn’t have much to do with broader
trends in Latin America?
I don’t think this had to do with the broader trends in Latin
America. Mexico has had a left-leaning party for some time now. López
Obrador was a very strong mayor of Mexico City and he built on that.
Between the collapse of the PRI which had a leftist element to it and
the presence in past elections of the PRD [López Obrador’s party],
that tradition had already been in Mexico.
