I was old enough to vote in the 1975 Referendum. My recollection then was that there was much more grumbling about the Common Market, yet there was a huge vote in favour.
In those days mass tourism was nothing like as big an industry as today. Now we have got used to our budget airlines and hen does in Alicante, and regular holidays in Spain and Greece. In short become much more au fait with other European cultures. So it's puzzling, except it's not - Farage whipped up racial hatred, Johnson had all his silly nonsense about straight bananas.
And don't let any Leaver think that Boris or Farage will be there to help them out when it goes tits up, because they won't - their aim will be to look after No 1.
