I’ve certainly seen stats that imply most if not all the ‘red wall’ has now flipped away from the Tories, thankfully including Haywood & Middleton which is a neighbouring seat. That was one of several that wouldn’t have gone if Farage/Banks hadn’t bought the Labour racist/nationalist vote to let the Tories in though (i.e. the seat fell by far less than the Farage vote).
As ever we are working with an incomplete dataset given people like Farage, Galloway etc can really have a huge impact on Labour without being legitimate parties with memberships, manifestos etc, but based on the existing market (Tory, Lab, LD, Green) it looks very much like these seats are now back with Labour.
The Brexit symptoms of rising food prices, obvious shortages, vastly increased energy prices, unemployment, poverty etc will hit hardest in these areas too. Really hard. The problem is Johnson is a well schooled Trump-clone popularist and I’m sure will go into the election with a range of totally uncosted popularist policies (minimum wage rises, duplicitous promises regarding funding the NHS along with anti-immigration rhetoric that is popular here). Like Farage he understands his marks well. He’ll make it very hard for Labour, especially if Labour continue with a strategy of deliberate nothingness.
