OK at the risk of bringing down the wrath of @Ruffers I am going to allow myself just a smidgeon of hope, at least up to the point where my idiocy is thrown back in my face.
Those of us who endured Johnson for eight years in London learned a few things about his governing style. Principally what he is is lazy and prone to waste public money on projects that boost his own ego. I expect that he’s going to continue that. So I think there is a very genuine possibility that he will distance himself from the ERG fruitloop axis of his party and eventually appoint a cabinet of (as someone said upthread) posh boy bankers.
Obviously that will still mean enacting some absolutely abhorrent policies and also ignoring crucial issues that threaten our society, but I think he will make an attempt to construct what he thinks of as a one nation tory party.
What worries me most I think is that he will try to consolidate his gains in the “Red Wall”, and the obvious way for him to do this is to go in hard on immigration. Once Brexit’s signed off and into the boring trade negotiation phase those voters will lose interest and turn their anger back onto the foreigns directly. But of course the tories know they can’t lower immigration without noticeably fucking the whole country, which is where the points system comes in. So he can keep the immigration at subsistence levels, but claim that he’s keeping his beady eye on them to make sure only the good ones get in. And that could/will end up a very dark place indeed.
Feel free to laugh at me when he makes Patel Chancellor. I’ll deserve it, but I just have to cling to some small hope that everything’s not going to be the absolute worst it could be.
