Having just got back from a couple of weeks in Scotland, the "Yes" voters are much more apparent. The No campaign seems to have a much lower profile and "No" voters seem afraid to express their views to their vociferous "Yes" neighbours. Based on what you see I think "Yes" could edge it. It is to be hoped though that the quieter No voters will simply turn up on the day and vote No.
Part of the problem for the No campaign is they have no cause and no credible "leader". The PM should be up there but, of course, given their hatred of Tories it has been felt he should keep out and also it would be wrong to have the English meddling in the Scottish vote. In some ways I think that is counter-productive as it suggests Westminster doesn't care about Scotland, which at the end of the day is in large part what this is about - distance and disillusionment with Westminster.
So, No is lead by a Labour figure and he doesn't seem up to the job, having no charisma.
Last weeks "debate", which I watched, was shocking. Salmond acted like a yob and just shouted down and interrupted Darling continuously. Nevertheless, because Darling was fixated with the currency question which the live audience were sick of he was felt to have been trounced. He didn't have the sense to change direction even when the audience were booing and heckling for keep asking about the currency.
I think it will be sad if they go independent. There will be lots of things that will change for us as well as them. One of the biggest losses will be the world's best flag! I think Scotland will become poorer over time and the rest of the UK poorer in the short-term. From a strategic point of view we lose a big chunk of our armed forces personnel and the US, fast looking East rather than to Europe, may lose interest in us.
One consequence may be the rise of English nationalism, which the establishment is always at pains to contain (although they may be happy to go along with to prevent independence movements in Cornwall, Yorkshire, etc).
A big threat to Scotland could be if they vote Yes and we get out of the EU. Then we could charge lorries crossing England to / from Scotland to use our M -ways (nice earner for Switzerland), could be trade barriers over time, etc if we are not all part of the EU single market.
Interesting times but I think a Yes vote will be detrimental to Scotland and us.
