The thriving constituency GMC has been taken over by Momentum. As part of their committee-packing drive, they replaced the LBGT rep - a cheerful gay chap whom everyone likes - with a straight, white male Union official. And they replaced the BAME rep - an Indian lady who'd been doing the job proudly and effectively for many years - with another straight, white male Union man. Incidentally, both of these carpet-bagging gits are middle aged, which isn't perhaps the image Momentum likes to project.
Multiply this a hundredfold across the land and I'm guessing the loyal-voter base quickly starts to erode, one way or the other. It could well be put to the test quite soon, we must suppose.
Over the weekend we'll have a look at what might be facing them across the political divide.
UPDATE: Makes this all the more amusing!
