It was a reasonable gamble that failed.
What I don't get, and didn't get with the Scots referendum either, is why on earth they didn't require a super-majority? Surely with something as critical as this, you'd want a bit more convincing than a 2% margin?
It doesn't have to be a 3/4ths or even 2/3rds, but a 60.1/39.9 split would've been nicely convincing that one side is definitely in a minority. Instead we've just proven once again that the UK is fractured politically North/South/Scotland/NI/etc.
And now you have a country split down the middle.
In 5 years time we'll just be talking about England alone. With maybe Cornwall and the North splitting from London and the South East.
Might be time to dig up my Scottish ancestry and get a dual passport...
If there's another Scottish independence referendum, Scotland would gain independence from a NON-EU country (UK) and then apply to join. This is similar to the situation with Slovenia, which gained independence from Yugoslavia and then joined the EU. Spain didn't veto that.
Very slim chance though, seeing as it was mostly the Labour heartland that voted for Leave.
Arguably, allowing a partisan realignment wherein people would vote for representatives balancing views on the EU with other policy concerns would have been healthier for the nation (if more disruptive to the elites of the existing major parties) than trying to preserve the existing party structure by splitting out the EU issue to a referendum.
And, it probably would have been more likely to succeed at keeping the UK in the EU.
