I have family up there (from Argyll and Bute to Fife), and they are not happy about the prospect of living in an independent Scotland. One cousin has even moved down south and changed jobs. She was working at the Faslane Naval base, which will most likely see massive job cuts should Scotland pull away from the UK, so she thought best to act now.
Salmond's a slimey bastard. He's trying to draw Cameron into debating with him because he wants to align and associate the 'no' vote with the Tories, who have next to no popularity in Scotland. He wouldn't dare debate with Millliband on the issue because Labour are popular up there. Lowering the voting age to 16 was also a dirty move; patriotism and nationalism are irrational sentiments which younger people are more susceptible to, and I can see that being the key factor in swinging the outcome towards the 'yes'.
Personally though, as a 3/4 Englishman, I couldn't give a turd what they do. There's a strong case to be made that England might end up being better off (the oil that Salmond keeps banging on about is managed mostly by British companies, so we won't lose out there). The Westlothian Question is also a massive problem for English democracy. Although, I totally understand their argument for keeping the pound; it's just as much theirs as it is ours.
I love Scotland, it's great, but we really don't need them. In fact, I'd probably vote for splitting the UK completely if English voters were ever given the same considerations and choices that Welsh, Scottish and Northern Irish voters are given.
