If you look at Wigan (my hometown) it’s part of the picture of why Labour’s never taken a strong leave or remain stance. Wigan’s been a safe Labour seat since 1918 but voted 64% for Brexit.
You can see the reason for the argument that if you’re stuck at the bottom of the pile, you’ll take whatever slim possibility of change is on offer.
The galling thing is though is that the hardline Tories couldn’t give less of a shit about the people who need the change the most. It’s criminal of them to pretend they speak for the people.
