That's funny because I don't remember the left abandoning Corbyn because of anti-Semitism. That's a very convenient lie, by someone who brazenly admits to being a backstabbing, conniving piece of shit.
It was obvious that Corbyn had problems that the mainstream media were never going to let him get past. Some were of his own making, undoubtedly. A lot, however, were continuously stirred up by the right of the PLP and the very people who now decry anyone on the left pointing out Starmer's manifold failings as traitors or tory-enablers.
Starmer will undoubtedly get elected, but he's showing himself for what he is now, a one nation 'small c' conservative.
Scared of his own shadow, a weak man, either bereft of ideas or lacking the courage to espouse them, all he can do is pray for help from the right.
I don't know how many traditional Labour supporters he'll lose, not enough to bother him at the moment clearly. However, I'm fucked if I'm going to let my vote be used to justify more austerity, low regulation, high inequality, bullshit - and make no mistake, that's what you're about to get, just with slightly better presentation.
