That was my impression too.
The no campaign should just concentrate on selling the positive benefits of the union, whatever they believe them to be, rather than trying to rubbish the very notion that Scotland could function as an independent state or claiming that the current Scottish government is somehow too stupid to understand the minutiae of how such a transition would work.
The current Scottish government has been sharp and successful enough to reach the point of offering a referendum on the matter. The real stupidity would be to underestimate them or patronise the Scottish people over the choice they have to make.
The yes vote are struggling to get 30% in the polls.You should see how skewed the poll that the SNP carried out was, it was full of leading questions and blatant trolling and even then they couldn't get more than 45%.
