Polls prove nothing. Having been a Buffalo public high school teacher for 30 years, I can verify that this fact is taught in upper-level science and math courses. Survey results, from a small sample, can only be used as indicators of the entire population if that sample is a fair representation of the population.
A fair representation of this country's population would include a sample from each of the 50 states, chosen randomly, to eliminate any bias. Otherwise, the survey is not an honest indicator of the entire population and the poll is a lie.
