The most interesting thing to me is how the pollsters could be so wrong. This was supposed to be close. Did loads of Scots wake up that morning remembering the disaster of Darien and think "oh ****, i'd better vote no"?
The pollsters didn't get anything wrong, as they were simply recording the information that they were given.
What happened here was that the majority of ordinary, discreet, gentle, kind Scots never once commented to anyone as to how they would vote.
The loud, partisan campaigning Scots made a noise for a few days, and then the quiet ordinary people crossed their ballot papers in the privacy and anonymity of the polling booth.
The pollsters just happened to locate themselves in predominantly loud, partisan areas. That was their mistake, maybe.
