This is not the best place for serious discussions but...The distribution of Leave/Remain voters has been pretty even before, during and after the vote. Which is why it was so difficult to predict the result. The number of undecided voters was very small. I have yet to meet anyone from that group. That includes people I know personally as well as those I met online. I have yet to meet anyone who has changed their mind since the vote. That includes people I know personally as well as those I met online. If there is any "buyer's remorse" then it must affect only the small group of undecided voters. If anything, the Leave voters I spoke to, either personally or online, are even more convinced that they were right. it might of course be a case of shouting louder to drown their own voice of doubt but they would never admit that. Given the vote went one way with such a small margin, even a small proportion could swing it the other way. However if a second vote were held tomorrow, I would not expect a decisive victory one way or another. It would be another 48/52.
