It's too early after the last referendum, they're just using the EU as an excuse.
It was a 10% split in 2014, seems the SNP want to ignore the wishes of the Scottish people when it suits them.
They can't have an independence referendum every time the UK makes an decision they disagree with, will they do they same with the EU? Of course not, they're single minded and only want one thing, they don't care about the consequences at this point.
That's of course if they join the EU, because that's unlikely itself, Spain has already said they will veto Scotland joining as they want to send a clear message to regions in Spain that want independence.
Part of me actually wants them to leave just so they end up in limbo, no UK, no EU... the Scottish economy will be screwed and Sturgeon and the SNP will be left in a horrible situation.
