You can only distort numbers, fudge responses, and use lies and misleading questions for so long before the numbers are meaningless. Maybe the pollsters just threw their hands in the air and give the fools the numbers they wanted to see, thinking they would never take the effort to dig too deep.
Absolutely agree. Your comment reminded me of the works of Immanuel Kant on deception. I have included it below.
