bullshit, total and utter bullshit; this campaign has shown that corbyn's policies are broadly popular and had there been a unified message from the moment he took over it could very well have been a different story
why do you think the tories are plugging the chaos s***? because that's the state the labour party was in for over a year with centre-right c***s spitting their dummies out because they weren't allowed to be tories anymore
It's never his fault. 
explain how it's his fault to get elected leader of the party and for factions within that party to sabotage his leadership and potentially hurt the party's chances of being elected?
they never thought he could win or even come close, so they didn't give a s***
he might well not win but to deny the impact of ther actions is wilfully ignorant
as for 'it's never his fault' corbs was losing me before this election was called if i'm honest, he wasn't 'leading' and challenging the tories enough in ways that were making a splash so he's certainly accountable for that among other things (continued support of abbott is a very poor choice when most of the electorate despise her, for example)
