You've illustrated very well the downside  (and the potential for manipulation) of statistical survey.

Unless one is alert to this potential (or/and has a background in statistical methodology and analysis ), he or she can easily be deceived.

Statistical science is a reputable discipline. Problem is it's full of disreputable people (that's not a statistic ) willing to skew a survey or two, and to tailor a question or two, to produce a skewed, and thoroughly unscientific result. And for what? Yep! For 'big bucks'.
