I haven't seen more than one or two in years that I agreed with.
Polls are dangerous even if honest.
Our system of government is a republic, with a written Constitution that is non-negotiable. That is the whole point of writing it down. Everyone, including government officials, are bound by it. The danger from honest polls comes from our representatives finding that we want something and giving it, even if it violates the Constitution, in order to get reelected. We then become a democracy, and in a democracy there are no safeguards for personal freedoms.
