But this is why the SNP polls are such a puzzle. I can't figure out why so many Scots (not all of them, Eric) seem to want to risk putting all of their eggs in one fundamentally separatist basket.
The polls are not reliable, imo. They are mostly taken from sub-samples of national polling. Then the media rams home this dubious message until people really believe it, and those tempted to back the winners will switch over. I think the SNP will benefit from this, no doubt about it. But I really don't think the entire Scottish people can have gone completely mad, not given their starting point as more rational and sensible than many other parts of the country.
I think Labour will do better than the polls say, because I don't believe people make such swift switches in allegiance, not in the absence of truly exceptional circumstances, anyway.
Possibly wishful thinking. But, for me, there is something deeply unconvincing about it all.
