This question has been settled with a final result: "No: Less than 45%". Trading has finished.
A recent ground swell of opinion towards secession in Scotland has taken most commentators by surprise. (Source?) Maybe due to increased risk of blow-back from Middle Eastern terrorists seeking revenge for British interference or maybe just a rise in nationalistic fervor in times of an unstable economy.
The feeling now among those in the know (Source?) is not a matter of Yes or No but a matter of Yes by how much of a margin.
Some polls (Source?) reflect over 80% in favor of seceding from Britain although this changes dramatically in different areas with those in higher class neighborhoods inclined to side more with the status quo. In reality a Yes is dependent on voter turnout as historically voter turn out in more deprived areas is low.
