Except Labour have offered a workable and very straight forward way of avoiding no deal. It may be true that some people would rather have no deal than accept that (Tories and some libdems), but that cannot be pinned on Labour. It is up to those people to explain why the impending shit show which may follow is a better outcome than Corbyn as leader for a short period of time.
I do think someone will crack here, ultimately. And am really not bothered by who it is. However, instead of trying to pick fights with Labour constantly, it seems to me trying to work together with the party at this point would be more productive. If, as many predict, it becomes impossible for Corbyn to achieve a majority, then that goodwill would likely have gone a lot further to finding a solution than what's happening now.
It's already impossible for Corbyn to achieve a majority. The 8 Tories and the 8 Labour MPs who've said they'd never vote for Corbyn under any circumstances puts it beyond all reach.
What you call 'picking fights' with Labour is really just being able to count.
And I'd have a lot more faith in Corbyn's dedication to no deal if he didn't manage to checks notes aah yes 1) become PM and 2) call the GE he's been blathering on about as a result of his plan.
If he were serious about this, his caretaker government would either revoke or revoke before GE, and he wouldn't insist on being leader of it.
At this point I don't give a fuck. I'm glad he's doing more than he was - credit where it's due - but that doesn't make up for the last three years of dithering.
