What proportion of the electorate went for UKIP in 2015, about 10%? And maybe another 40% for the Tories? How many of those twats are going to change their minds?
Brexit is going to be a massive failure. It couldn't possibly be anything else - the UKippers and Tories and Labour voters and miscellaneous who voted for it have nothing else in common except voting to leave the European Union. There is no possible deal that would please all those different groups of voters.
The whole thing is just a distraction - Brexit will happen in one form or another, there will be some kind of deal worked out in which things are mostly the same but a bit shittier, a lot of people will lose their jobs, and we'll still be here 5 years from now complaining about the same old shit. The amount of electable anti-austerity workers parties built will be zero, the amount of rich people getting richer will be immense, and the amount of poor people getting poorer will be even more immense. And that will be partly because people who could otherwise have made a difference spent their time concentrating on this stupid Brexit shit instead of anything that will actually change anything.
That's how I see it, anyway, I'll be very happy if I get proved wrong.
