Polls are created and skewed to get certain results to fit a specific agenda. Polls are junk. Worthless. Useless. Garbage.
They are not "worthless" insofar as getting legislation and laws passed however. They are part and parcel of manipulation of the worst sort. Humans have a herd mentality and don't like to be outside of the mainstream. The trick is in getting the vast majority opinion holders to somehow believe they are a tiny minority. In that the social engineers have been wildly successful. Polls are designed for this purpose.
