It’s a nice graphic, but it’s not a true picture as loads of seats weren’t up for grabs. Labour ‘retained’ Wigan because two thirds of seats weren’t electable this time. Of the 20 Labour seats that were contested, they lost the lot.
I don’t think anyone should try and minimise the threat from these turds, although I don’t believe it’s as big as the media would love it to be. As I said earlier, their vote share peaked last year and is falling, and also if first past the post is retained they will crash and burn with tactical votes and Flange as PM frightening all the horses. Still, best not to underestimate the stupidity of our average Briton.
