Professor John Curtice, perhaps our foremost psephologist, has written a piece on current polling for the website UK in a Changing Europe (HERE) with the title Has the Election seen a change in attitudes towards Brexit. It makes interesting reading because it summarises a lot of accumulated polling since the referendum last year. He does not conclude there has been a big shift in opinion, he was more nuanced than that. This is the key sentence - "In short, while there is some reason to believe that there might have been a small swing against Brexit, the evidence that this has happened is still not wholly consistent".
However, what Professor Curtice does say is there has been a huge shift in the public's confidence that the government will get a good deal. This has, he says, been dealt "a severe knock". There has been a 10 point swing against the government since the election on June 8th according to ORB. And YouGov now say only 24% think the government is doing well in the negotiations compared to 51% who think they are doing badly. I expect the gap to widen further as time goes on.
The government has done little or nothing to manage expectations and they will pay the price for misleading the public about the kind of deal we can get and the strength of our negotiating position.
