Polling is dead. See: http://www.people-press.org/2012/05/15/assessing-the-representativeness-of-public-opinion-surveys/ which reveals 91% of selected respondents end up not responding (leaving it all to the 9% who push all the right buttons) and http://www.gallup.com/poll/158066/special-report-adults-identify-lgbt.aspx (which makes it possible for a very small group ~ gays ~ to respond as though they have 10X their number ~ just by making sure they answer or call back each and every poll that might contact them).
Word. People who allow their opinions to be shaped by polls are merely 'useful idiots'.
