Granted it is a resource. However polls are no different than surveys....all are/can be designed to reflect a desired result. Too many controllable variables; where taken, by whom, number of participants, environment where taken, how asked, what was asked, etc., etc.
Most are ever true statistical representations of reality.

It is said if enough of them are done consistently in the same manner in many, MANY locations and repetitions there may (MAY) be a pattern detectable.

Therefore, polls (or surveys) add no value (for me) in evaluating anything of significance.
