Doesn't look obvious to me: many polls show a majority for Remain, but not by such a wide margin: 12 percentage points at best. We're not talking a 2/3 - 1/3 majority (and for some polls, the gap narrowed recently to 5%). I remember that the polls were predicting a clear Remain majority for the 2016 referendum.

If anything, the British society is still very divided by the issue: it is more than a fascist minority.
Would the present Remain majority survive a second referendum? This would turn into a heated controversy about the establishment respecting the results referendums in the first place...
