From The Patriot Post editorial dictionary:

Pollaganda — n. 1. mainstream media (MSM) polling used to manipulate public opinion and advance a particular bias. 2. Outcome-based polling; instruments designed to generate a preferential outcome, which can be used to manipulate public opinion by advancing the perception that a particular issue, individual or group has a majority of public favor or disfavor. 3. A dezinformatsia (disinformation) campaign of political polling used for propaganda, polling masquerading as "objective journalism" designed to advance a liberal bias.

Pollagandize — v. 1. To engage in pollaganda. 2. To utilize instruments of pollaganda, or selective poll reporting (reporting polls that comport with a particular ideological viewpoint), to advance a bias.

Pollaganda Cycle — n. A self-perpetuating cycle — the intentional and systematic propagation of MSM polls to manipulate public opinion by first saturating viewers with "reporting" that reflects a particular bias; second, conducting public opinion polls in concert with like-minded organizations or campaigns, which will reflect that bias; third, further proselytizing viewers by treating these poll results as "news"; and fourth, using pollaganda to induce "bandwagon psychology" (the human tendency of those who do not have a strong ideological foundation to aspire to the side perceived to be in the majority), thus further driving public opinion toward the original media bias, ad infinitum.

Pollaganda depends on outcome-based opinion samples (polling instruments designed to generate a preferential outcome), which in large measure, reflects prior-opinion indoctrination or cultivation by the same media conducting the poll. The incestuous results are then used to manipulate public opinion further by advancing the perception that a particular candidate or opinion on an issue enjoys majority support. The MSM presents such polling as if it were completely objective.

The "Pollaganda Effect," refers to the use of polling as propaganda. This term refers to political polling which often masquerades as "objective sampling," but in fact includes a particular bias — who is asked what and how. That bias can be driven by ideology, advertising revenue or both — which is to say that any commercial media outlet has an inherent conflict of interest in its polling. The Pollaganda process, then, is cyclical and self-fulfilling. The net result in the 2016 primary campaign was that, at every debate, poll standing has put Donald Trump standing center stage. And consequently, the MSM is, in effect, choosing the Republican nominee.

If you find it difficult to grasp the "bandwagon effect" of political poling and the self-fulfilling cycle it creates, consider this. Virtually every media outlet refuses to publish entrance or exit polling from the time polls open until they close. The standard reasoning offered is that the media does not want to influence the outcome of the election — because they know such polls will either motivate or deter some people from voting. However, the same MSM outlets inundate voters with polling up until the minute election-day voting begins, as if somehow that polling does not influence voters.

So much for the "free examination of public characters and measures." When confronted with the next headline or talkinghead report about the latest poll results, caveat emptor!
