Earlier this morning we wrote about the obvious sampling bias in the latest ABC / Washington Post poll that showed a 12-point national advantage for Hillary.
Like many of the recent polls from Reuters, ABC and The Washington Post, this latest poll included a 9-point sampling bias toward registered democrats.
“METHODOLOGY – This ABC News poll was conducted by landline and cellular telephone Oct. 20-22, 2016, in English and Spanish, among a random national sample of 874 likely voters. Results have a margin of sampling error of 3.5 points, including the design effect. Partisan divisions are 36-27-31 percent, Democrats – Republicans – Independents.”
Of course, while democrats may enjoy a slight registration advantage of a couple of points, it is nowhere near the 9 points reflected in this latest poll.
Meanwhile, we also pointed out that with huge variances in preference across demographics one can easily “rig” a poll by over indexing to one group vs. another. As a quick example, the ABC / WaPo poll found that Hillary enjoys a 79-point advantage over Trump with black voters. Therefore, even a small “oversample” of black voters of 5% could swing the overall poll by 3 full points. Moreover, the pollsters don’t provide data on the demographic mix of their polls which makes it impossible to “fact check” the bias…convenient.
Now, for all of you out there who still aren’t convinced that the polls are “adjusted”, we present to you the following Podesta email, leaked earlier today, that conveniently spells out, in detail, exactly how to “manufacture” the desired data. The email starts out with a request for recommendations on “oversamples for polling” in order to “maximize what we get out of our media polling.”
I also want to get your Atlas folks to recommend oversamples for our polling before we start in February. By market, regions, etc. I want to get this all compiled into one set of recommendations so we can maximize what we get out of our media polling.
The email even includes a handy, 37-page guide with the following poll-rigging recommendations. In Arizona, over sampling of Hispanics and Native Americans is highly recommended:
Research, microtargeting & polling projects
– Over-sample Hispanics
– Use Spanish language interviewing. (Monolingual Spanish-speaking voters are among the lowest turnout Democratic targets)
– Over-sample the Native American population
