"This is why you can get reliable polls even if you ask fewer than 1 in 100,000 people."
Ahem:- polls *can't* account for people like me who refuse to take part in polls, they can only assume a pattern of behaviour and/or beliefs for people who refuse to participate.
I *am* the error bar.
*EDIT*:- There is no way to correlate the projection of the poll against what I believe or do. How are you going to check, take another poll?
