The next time Labour win a working majority in a General Election, if ever, it'll have a basically Blairite policy offering—minus most of the identity politics—a persuasive leader, and far fewer racists, cranks, and wannabe communists. Everyone knows this, but pretends otherwise.
So, instead of quickly jumping to this final, winning, position, we'll endure years of endless hand-wavy debates about "what Labour means in the 21st century" and tedious flirtations with regional devolution, and PR, and "smart nationalisation" and "green growth" bollocks.
Right now, we're watching a fella who has just come through the mother of all ugly, racist, relationship destroying midlife crises. And, now, instead of him cutting his hair and settling down with a good woman, we're going to have to put up with him doing 10 years of therapy.
