"If this is the sort of scaremongering HMG are going to indulge in over the next two years the whole debate will be reduced to a farce."
That will happen anyway. It's the nature of these things, and it's inescapable.
I would venture a guess that most Scots have already decided how they'll vote, come referendum time. There will be a few wobbles along the way, but all the propaganda and TV debating is unlikely to make much of a difference to the result. It will probably narrow the gap, but that's all.
