I certainly agree with your point about 60-40 being easier to accept for the losers.
It's a difficult question especially when the vote is about something so emotive. Maybe they should have had a referendum about the referendum rules. Hang on a minute.....
And for that reason I still feel that it should have been campaigned with lots of real numbers thrown around. Then at least the emotive ones who wanted to leave, might still want to leave and wont vote cos they know its dumb? What we gain, what we lose, all in STG. Immigration in bods and STG. Everyone can understand that. But it seems many took the heart approach. Anger votes.
