I do.
I also think that even if there was another ref (There shouldn't be) ... the longer this goes on, the more would vote for Mays deal in the absence of any other real alternatives, partly as a protest but mostly because it's reasonable, perhaps with some small amendments.
Free movement would be a key and personally I think even more would vote to stop this.
Many don't understand that being part of the customs union, as suggested by some (and not dismissed out of hand by myself) would mean Britain can not independantly negotiate trade deals with the rest of the world but many are concerned with things closer to home, rightly or wrongly.
Just this will almost certainly preclude most already mentioned ways.
Pie in the sky. There will be no second referendum.
