I think it's quite mixed. Initially I felt a fair bit of sympathy for Corbyn - a lot of the centrists in the Labour party had it in for him from the start, and the media have often tried to portray him as some batshit socialist when he's probably more of a democratic socialist who really isn't that out there in regards to what he'd do economically etc.
But he's not done himself any favours. McDonnell as Shadow Chancellor. Diane Abbott in important positions at all. The weird thing with the train where he tried to pretend there were no empty seats when there was. Sending Abbott to an interview without her actually having any idea of the figures she was trying to defend. Shite like that just gives his opponents more and more ammo.
And while I have sympathy for him, and for some of his supporters, because I ultimately agree with a large part of their agenda and sympathise with their case, there comes a point when they need to look inwards and say that, yeah, for all the infighting, and for all the press bias...he's been a bit shit, has made some shit choices, and really hasn't been anywhere near as successful as he was supposed to be.
And while it may be shite for them to have to acknowledge failure, and to potentially have to concede power back to the centre-ground, they should also realise that the electorates problems are not tailored to what happens to the Labour party - yeah, it might be crap if other people are trying to oust you from power and undermine you, but it's ultimately inconsequential to the country as a whole. If Corbyn can't win, or can't prevent a massive, massive Tory majority...then why should I care what's happened within the party? All it ultimately means is a gigantic win for the Tories.
