Polling firms survey around 1500 people (PDF) (http://www.publicpolicypolling.com/pdf/2015/PPP_Release_National_90315.pdf) to predict a national election. They are batting over 90% accuracy. We had over 10,000 paying members, 6,000 of whom voted. That seems to be a good sample of science fiction fandom.
