He was the most visible Labour politician throughout the campaign, attending more public clinics than the shadow cabinet combined. I absolutely agree that he could've done more, but it's very rich for the parliamentary party to even criticise his lukewarm efforts - let alone claim their coup is predicated upon them - when they did absolutely nothing themselves.
These waters are much more murky.
The Tories must be pulling strings for the Labour unrest to continue :D I bet they are gleeful as fuck, it's all they could wish for. Corbyn winning for them would be a blessing. Why don't the Corbyn supporters see this? They are like some crazyfans supporting a team manager, for whom the players refuse to play.
What do the Corbyn voters imagine will happen after Corbyn gets reelected? How do they see the future of the party? This is a protest vote that solves nothing, like some teens smashing stuff to show they're angry...and then made to clean up and being deprived of the things they smashed.
