Don't be silly. That just proves you dont listen.
LibDem Remainers didn't do the tactical voting expected (certainly in our constituency). That was what we needed to compensate for the anti-Corbyn factor costing us so many Labour supporters, and it didn't happen. Few mentioned Brexit as a factor even when pressed, but I was mostly canvassing in a relatively "comfortable" area rather than the ex-council wards where the Tories didn't win but picked up a lot more votes than usual.
You'll have to excuse me if I don't bother further with analysis, as there's no point. No votes to be gained.
I don't think Johnson even needs to fulfil the one-nation guff. Boundary revision, based on registration that favours the well-off (people in their own homes rather than the poorer rentier class), will go ahead - though if those areas are now Tory seats maybe they won't!
And if Momentum controls the leadership campaign and really can't see that Corbyn was a disaster, it's hard to see much of a revival if the same "popular" policies remain under any leader.
If the PLP could choose its own temporary leader that would help, but Corbyn staying on means he chooses a new shadow cabinet.
