I think that the assumption that if Scotland goes for independence that means the Tories will have a political boost because there won't be the Labour votes from Scotland could be a radical misjudgement. If the Scots vote for independence I can see the English political system going into meltdown, and a new political settlement coming out of it - with the Tories not doing too well in it.

The psycholigical reality of the realisation that there no longer is a country which can be called "Britain" could be quite dramatic.
