One doesn't have to get through a paywall to see the article in full, though thank you to primrose for précis-ing it.
All I did was register with the Telegraph for the ability to see a small number of articles per month. It doesn't cost anything and every once in a while, as with Chakravarty's article here, there's something I want to check out if I see a reference to what looks as if it might be interesting on Twitter.
What I agreed with is what Chakravarti wrote: that the commonly expressed view by people like Vince Cable that Brexit voters are old, uneducated bigots and racists is completely wrong. People have been taken in, willingly and as usual, by twisted statistics.
