I’ve heard a lot of people make the point that it’d be political suicide if the government declares brexit a bad idea and then backtracks, ignoring the referendum and thus remain in the EU after all, that it’d feed into the hand of the nationalists – but I’ve got hard time understanding why? Doesn’t this assume that people are just dumb? That hey believe the government has been sitting on their hands in trying to get a deal done, and not really, I mean really tried? Isn’t there an argument to be made that they did try, and here are the results, and because of that they’ve concluded that it’s a bad idea? Is it really so hard to believe that a majority of the UK voters wouldn’t accept this, when it was such a contested referendum result in the first place? Especially so when the referendum question was only discussing leaving the EU, rather than promising any particular outcomes? I’m having a hard time believing that a majority of people in the UK are so entrenched that they can’t possibly change their minds given the light of new facts, hat everyone will turn to nationalistic agendas, and that the referendum result of two and a half years ago is still a valid gauge of popular sentiment.
