Ask any election strategist and they’ll tell you that momentum is everything.
For the past 18 months, the No campaign has had all the momentum in the referendum debate. The Yes camp were becalmed, the No side had everything going for it and (let’s be honest) there was more than a hint of complacency on the unionist side.

Well that there was should have been blown out of the water by what has happened over the last couple of weeks. Subtly, almost imperceptibly, the ground has shifted in the independence debate. The Yes camp has not bounced into a lead or anything like that, but it has started to make progress.

A poll this week by Survation for the Scottish Daily Mail in the wake of George Osborne’s ‘You can’t share the pound’ speech showed that the gap between the two sides had come down to nine points.
