The proportion of the grey vote (and nearly grey vote) was always a shoe in. That would make up half of the leave vote. They didn't need persuading. Neither did the actual people who suffered in the jobs market. Similarly the half a million actual racists / bigots (which is smaller than most other countries) did not need persuading.Imps, so 5-6M on the jobs bit, max and that might be being very generous. That still isn't the majority of the leave vote. There are lots of other reasons people voted, but my bet is, was and always has been since they announced we were having one, that he best rhetoric will win/won.
This like most close votes was about the 10% of "undecideds" and no-one knows how many of them were not undecided and "shy"leavers.
It is all very well the young saying they have been betrayed but when less than 40% of them voted how many of those that are complaining didn't vote? And why not?
I think that it needs to be understood that there are a lot of people these days that have views that others try to suggest are shameful and so you get lots of undecideds which aren't really undecided. They are people that do not want others calling them names for having an opinion different to theirs. This is the second vote in 2 years where a large proportion of the undecideds weren't undecided. They were just "shy". It is patronising to be told that x party or x leader needed to be more vocal and that people would follow like sheep.
