Scotland may have less than a tenth of the UK's population, but we still pose a huge problem to the 'Out' campaign in the EU referendum. The most recent YouGov poll suggested that the 'In' camp have a whopping 36% lead north of the border. If Scottish voters were breaking in the same way as everyone else, the overall UK-wide lead for 'In' would be 2-3% smaller. That could make all the difference in a tight contest.
So where are 'Out' going wrong in these parts? Frankly, the archetypal Westminster Eurosceptic you see on the TV is utterly tone-deaf in his approach to Scotland. He (and it usually is a he) sniggers at the desire of so many of us for independence from London, and asks "how can it be 'independence' when you'll still be ruled by Brussels?". To which the obvious response is : "OK, so you support 'real' independence, then? You think we should be independent from both London and Brussels?" And the answer, of course, is no he doesn't. He wants us to be ruled from London, not Brussels. He possibly doesn't think the Scottish Parliament should even exist. At that point we just stop listening.
If that guy is the face of the 'Out' campaign in Scotland, it's hard to see them making much headway. A minority of independence supporters (and Devo Max enthusiasts) will still vote to leave the EU, but they'll do it largely in spite of the official campaign, not because of it. But supposing a radically different approach is taken. Supposing the 'Out' campaign in Scotland is mostly separate from the English campaign, and distances itself completely from the British nationalist pitch being made down south. Supposing the head of that campaign is someone who is known to be sympathetic to independence, and who is able to sound completely authentic when he says something like this -
"Our campaign team contains people with a range of different views on independence, and that issue is for another day. What unites us, however, is that we all want to see the Scottish Parliament become much more powerful, regardless of whether it is an independent or devolved parliament. And it is simply a fact that an 'Out' vote will, at a stroke, make the Scottish Parliament far more powerful than it has ever been before. Westminster is prevented from interfering on devolved matters by the Sewel convention, but there is no such constraint on Brussels. Every single day, the Scottish Parliament and Scottish Government are prevented from acting on devolved issues such as health and fisheries because of suffocating EU law and regulation. An 'Out' vote will at last give Holyrood control over these issues in practice and not just in theory."
I doubt if that will happen, but it could be a game-changer if it does.
