nostr:npub1g0tuf634rz4suczwj7kgnecr6cyt0eu9xmp3sp0fku68mqehq4msp3tvm4 The EU problem for Labour for a long time was that 
1) The majority of Labour voters were pro-EU
2) The majority of Labour constituencies were pro-Brexit

That's no longer true.

I had Momentum insiders tell me they couldn't possibly come out and be anti-Brexit because it would destroy them in the Labour Heartlands. That wasn't true even then. But they believed it.
