conducted and evaluated with prescribed statistically valid processes, regardless of who conducted it, it would indicate to me that there must be a lot of stupid folks out there or, maybe as I should have said, just providing bogus answers.

As you say there are polls upon polls out there, the results of which can and most likely will change each time it’s replicated. And for that matter, how many folks actually answer polls as to how they actually feel on a matter, with some deliberately providing answers contrary to their beliefs?
