It is good how everyone can call the same number in different ways, I would call the hypothetical 60% votes for re-join as a "slight majority", the FT calls it a "strong approval".
So to get to the point, has anyone changed their mind, or is this just brexiteers dying?
But for getting 60% or more there is anyway the need of lots of people changing their mind.
I still believe (maybe wrongly) that part of the reasons why Brexit succeeded was because the voters were not properly told what the advantages and disadvantages could have been, so a certain number of people voted for Brexit without really-really being convinced.
The debate was over a hard or soft Brexit. Even the hard brexit was softer than what we got.
Bush jr didn't get a majority and in blighty in the last election the Tories 'won' with 43% of the vote, which netted them 56% of the seats.
