'Soft' is an appropriate label for much of the Labour 'left', as in a bit 'soft' in the head. They seem to be 'lying low', adopting a 'pragmatic' approach until the next election, where the priority, of course, is getting the Tories out. Even if that means replacing one set of Tories with another set of Tories, but of a marginally different hue of blue! If that means, for the good of the Party, that they sacrifice Corbyn, well, that's a price they are willing to pay.
