I know it is one of the so called special circumstances but I'm not sure about that causing another vote. I think there will be another referendum but not until they are pretty confident of winning it. They could brush away the loss of the first referendum a bit because all in all they did well - coming from way behind to a much closer result in the end than what was expected. They couldn't afford to lose a second though - that would kill the question off for decades. So just my opinion. I know the latest poll showed a clear majority for independence but I think these results will need to be consistent over a period before it'd be considered. So not as much if the UK votes to take us out of the EU against the Scottish opinion (if that was indeed different from the remaining UK) but more how Scottish opinion actually reacts to that scenario. I don't think the forthcoming SNP manifesto will promise a referendum but I think it may state it retains the right to hold a referendum if they have a mandate in Holyrood.
