I think the Scots will side with caution and vote NO. Many wealthier Scots - businessmen and the middle class - won't risk their necks and investments and financial futures just for the sake of a thistle on their passports. Money speaks louder than any politician! I just can't see where the SNP can gain YES votes on this issue.
If I was Mr Salmond I'd try and argue on principles - Scots have not voted for the Conservatives for decades yet Westminster Tories dictate!! That's not democratic at all. That's a fundamental flaw and it needs highlighting.
I'd appeal to pure emotion - history, being a sovereign country again and having the political freedom many Scots crave.
Cameron, Osborne & Co won't let go on this one, they've too much to lose. They'll hammer away and tell the Scots NO Sterling Zone, if they vote YES.
Is this rhetoric a bluff? Could be, but it'll scare the fence sitters into voting NO.
Barroso seems to have vested interests too. The EU don't want the UK broken up for obvious reasons - instability and potential chaos at a time when the Eurozone is still fragile.
Interesting times ahead. Kilts and sporrans at the ready!! Dirty Tory tactics inevitable!
