Or has red wall left because connection to grassroots/unionism has been lost and the memory of Thatcher has faded enough that the stigma of voting blue has been removed?

Red wall left because "you've done fuck all for us" and have gone Brexit / Tory.
BLiar mob left and probably went libbdem/Tory
Blair did wrong went green. After libbdem dalliance.
