“Polls are for
dogs” is an adage ascribed to Progressive Conservative John Diefenbaker,
Canada’s 13th Prime Minister. It is a view that voters ought to embrace, too,
especially during election campaigns. Diefenbaker likely wasn’t leading in the
Polls when he made that quip, but there is still merit in the remark.
Polls, as does the public. Who doesn’t want to peer into the future? My advice:
don’t take them too seriously. There are many reasons why they will have no
relationship with the outcome of the May 16th General Election.
latest Poll from Abacus Data, giving the PCs five percentage points over the
Liberals. A week earlier, an MQO Poll gave the Liberals a 12-point lead (among
decided voters, 48% to 36%) with a 39% undecided factor.
In a campaign that is
as dull as a debate over whether Dwight’s or Ches’ hair colour is darker,
change hardly seems a disruptive influence. Yet a couple of days later, a third
survey — the Forum Poll — gave the PCs a 2-point lead over the Liberals. Forum
even went so far as to predict how many seats would be won by each Party
despite offering no regional breakdown — hardly a nod to statistical science. Even
if it were, in the world of statistical analysis, the “regional” breakdown of
the number of eligible voters questioned (the sample size) would be too small
to have a meaningful level of accuracy.
Why the big
difference in the Abacus data vs. the MQO and Forum Polls? The proffered reason
is that the Leaders’ Debate was an intervening event. If that is correct, then it is baffling that
there was not a single moment when Aunt Bessie could be seen biting her nails

basis of Polls is really the only constant in the survey process. The process
of achieving statistical accuracy is actually very difficult. It relies as much
on art as science. In particular, privacy issues; the reluctance, especially in
urban areas, to share personal information (long a problem and getting worse);
the reduction of land-lines in residential homes; and caller I.D., which enables
the screening of nuisance calls, are reducing the probability that a survey sample
of potential respondents is representative.
MQO’s VP, in
providing a regional breakdown of his data results, urged “caution in some
areas dues to limited samples available.” That was prudent because the margin
of error that results when the sample is reduced to regional representation, as noted, can
completely distort the result. A bigger question, I suggest, is whether the
margin of error applied even to the whole sample fully reflects the challenges
of modern-day polling practices.
inquire if recognized Pollsters are associated with one political Party or
another. For example, Wikipedia confirms Tim Powers, a Tory strategist and
Nalcor Consultant, as Abacus Data’s Managing Director. The evening before the Abacus
Data Poll was released, he tweeted this comment to NTV’s Michael Connors: “Our
@abacusdata will be out tomorrow. Again watch for sample size, dates of
polling, trends. MQO is a good firm don’t question their data.”
data? Shouldn’t ostensibly independent Polls have a degree of separation or two
from partisan hacks? (Tory Organizer John Laschinger should kick his ass for this!) Is there no difference between “our” and “their” data? Of course, Abacus has a foot in both Camps. Its Chair is Bruce
Anderson, father of Liberal PM Justin Trudeau’s director of
Communications. Look deep enough and you’ll likely find that at least some of the other Polling firms have similar relationships with the political Parties.

they were the holy grail, people should take a deep breath and give a nod to John
suggest that Polls are worthless. True, many given prominence in an election
campaign are attached to the latest Campbell’s Soup survey, gathering only
limited data on voter intentions and leadership likability. They return a
relatively superficial snapshot of current voter thinking.
polls — no differently than those conducted in other fields — is found in those
that assist a political Party to define its support, taking into account gender
and demography as well as geography when defining voter preoccupations and
assessing trends. This deep-dive into the public’s political preoccupations requires
a lengthy and detailed questionnaire and extensive cross-referencing of data — all of it overlain with traditional and
current voting patterns, or some other set of statistics that helps produce an
informed narrative describing voters’ thinking.
In contrast, the “Poll
Results” offered up for free from any of the commercial pollsters — all
liberally broadcast by the media — are little more than titillation for the
masses. During elections, they are intended to influence “outcomes” far more
than to make a contribution to the democratic electoral process. For the larger
analysis, the political Parties pay big bucks.
more than the relatively high disapproval rating ascribed to the Party leaders,
voters should be concerned about the huge “undecided” factor — which, i n addition to voter turnout, threatens a far larger impact on the election outcome than the results of any highly

a matter over which a select group always seems preoccupied — be content that
