Here’s the way I look at it.
According to what I’ve read, older people voted to leave. Now, older people do remember what Britain was like before the EU disaster. A free Britain, able to forge trade deals, border control and so on. They wanted those days back.
The stay people are primarily young millenials who grew up in the EU and have no frame of reference other than that. They are/were in their comfort zone, their safe place with the EU. They are deathly afraid of change and blame the older people for leaving.
That said, those same millenials couldn’t be convinced to get off their as*es and go vote. Why should they. The “polls” said stay was up (by some polls) 8 points. It was a given, so they stayed home. Now that they’ve lost, they want a do-over.
I say, sit down and shut up millenials, adults are now in charge.
I hope Hilda leading by 14 points in a recent poll, the same will repeat here.
