I've just been going through the list of Conservative gains from Labour. Highly consistent pattern where the Labour party vote share as down 10%, split three ways between Tories, Bxp, and Lib Dems. Most of them they could retake just by reclaiming vote share from Lib Dems and Bxp.
This narrative that the labour manifesto was far left needs to end. They were sensible, popular policies that will be good for everyone.
