Say there is a GE called early next year, now do you think Corbyn potentially losing that would do more damage to the Labour party than a split would? Or even a coup than turns the grass routes away and offends some of the public on principle?
If anything the circumstances of an early election have reduced the time they would have had to put up with him. We're not waiting 4 more years and risking another 5 of Tory governance.
I can imagine you dislike Corbyn as much as I hated LvG but even I didn't want us to concede own goals just to be rid of him
