> I did and that’s not how polls work.
Since that is exactly how polls work, not sure how you could have read it.
> Those numbers are much closer than 60/40, for a start
Only because I lumped all of the "Don't Knows" into "Leave". Which is unrealistic, but a lower bound for the vote for remain that is above what you claim. So your claim isn't just not right, it isn't even wrong.
If instead I lump the "Don't Knows" in with "Remain", it turns into 68/31. The truth is probably somewhere between 55/44, which is still a 10% spread, and 68/31, which is 37% spread. And 60/40 is not splitting the difference in the middle, it is giving more of the undecideds to leave.
> To get elected, you win constituencies, not the popular vote
To leave the EU, you win the popular vote in a referendum, not individual constituencies. To rejoin would most likely be the same.
And it turns out that the result is even more lopsided in thinking Brexit was mistake when you look at constituencies. In effect the entire country is now Remain.
