The engineered polling results are deployed as a false witness, they give cover to what THEY would have us believing. Ideally for them it would create a self fulfilling prophecy, or like steering a cat around with a laser pointer. We know what we know, but are still very susceptible to being influenced in our model of what those crazy other people believe. It's a man in the middle attack, and going by how often they use it, it must have been working. Be advised.
