Looks like the chimpanzee "users" aren't too smart. The polls were so accurate in predicting Romney's win and more recently, Clinton's.
The fact that there are inaccurate polls, does not mean that all polls are inaccurate. The fact that the media puts out "push" polls with a deliberately slanted outcome does not invalidate all polls. And the fact that many misinterpret the meaning of polls, does not mean that everyone is unable to use polls to gage public opinion effectively.
Your argument is akin to saying that because Vegas gets a betting line wrong on occasion, it is always wrong when it sets the spread for athletic events...logic and scientific method would argue that that is a childish and ignorant opinion. Foolish people often dismiss that which they do not understand.
As it turns out, the internal polling of the Trump campaign was very much on the right track with regards to the upper midwest states...and is what prompted him to heavily engage in that area...leading to his victory. Polls are not predictors, nor are they Gospel...they provide probabilities in a given moment in time IF their methodology is sound and they are not deliberately being used to achieve a desired result. The process is complex and imperfect...and incredibly useful to a campaign and/or candidate.
