The Tories are also a power-driven party almost entirely untroubled with ethics. They understand that the bottom line is winning an election, and they do what's necessary to win it. The number of Tory MPs who deeply believe in anything and will really stand up for it is usually so small that "division" rarely impacts where it counts. Two thirds to three quarters of Tory MPs were against Brexit. And the minute the referendum passed, they happily fell in behind May and went about implementing a hard Brexit, derailed only by a small minority who weren't satisfied with how hard it was. And then in the final analysis, how many really stood up and said no to Johnson in 2019? 20? And what did that purge cost Boris?
Johnson is a lazy, incompetent and probably corrupt buffoon, albeit sort of popular. The Tory MPs knew that. If they didn't know before May made him foreign minister, they knew after: he was well known in political circles to not have been up to the task. And yet when May fell, they took a look around with their only real consideration who would win the next election for them: Boris had the right kind of popularity. Because fuck the country, they want to win and if they hand it over to a fool, so be it. They want to win so much, the Conservative and Unionist Party (to give it its full name) would betray its own values by driving Scotland to independence, because it sure as hell shows no apparent awareness of the crisis its actions are causing to the union.
And then we get Labour. There were all sorts of dodgy shenanigans in the 2010 leadership election that saddled it with the lacklustre Ed Miliband. And then Corbyn wins the Labour election, and the Labour centre sets about sabotaging him. Then Starmer comes into office, and the Labour left sets about sabotaging him. Labour is full of complacent, myopic, impractical ideologues more interested in their own internal power plays and hunting down supposed heretics amongst their own than delivering a better country for the British people.
To make this metaphor for the British Labour Party complete, imagine instead of Slaeeshi porn that the parchment contains progressive policies the electorate want.
