You're right. It's getting more towards a narrow church... with a smaller congregation, who either agree with Boris or aren't prepared to say otherwise. There are some mutterings about how many of each.
I wonder what the longer-term ramifications of this will be. Is this the Tories redefining themselves and moving further to the right of UK politics, or will this seem like a spat in hindsight post-Brexit? It's looking pretty incendiary at the moment. I'm a little younger than you, but I can't remember anything like this.
