I can't even fathom how anyone could think voting for Boris deal is common sense. It would be an act equivalent to the Lib dems turning on their own voters to join the Tory government.
It's telling that it's mainly the Labour MPs stepping down that are saying they'll vote leave. I'd be very surprised if they dont get favourable jobs in the future.
How many Labour MPs do you think will vote for it? Think 3 have already said they will (Mann, Campbell, Fitzpatrick) and then you have the likes of De Piero, Kinnock, Nandy who probably will. I think they could end up with around 8 or 9 Labour MPs.
