Yeah, fully agree. The messaging was really disappointing this campaign. The policies were not presented coherently, instead the strategy seemed to be vomit it all out at once and hope that there'd be something in there for everyone to latch on to. Even as someone who agreed with the vast bulk of it I struggled to become especially endeared to the proposals. They definitely lacked a flagship policy and an overarching message/slogan. Felt too much like a reheated, chaotic and underwhelming branding of what they did two years prior. We all know the scrutiny that the media and commentators are going to apply to any left-wing spending plans so it's essential Labour deprive them of as much ammunition as possible.
Yes, certainly the often blunt response to centrist/Blairite voices by many on the left needs to be tempered. Right now it is imperative that the division is bridged as much as possible. But let's not pretend that this was one way problem. Unprecedented hostility from within its own ranks has also been a hallmark of the Corbyn era for Labour. There were numerous MPs who never gave him a chance. The likes of Ian Austin showed their true colours by ultimately endorsing Johnson. It's unforgivable that anyone who claims to represent (or have represented) Labour's values can openly advocate voting for the Tories, especially in its present incarnation. I cannot comment from a position that is not clouded with bias but I sincerely feel that the divisive rhetoric and self-sabotage has stemmed from the centre's unwillingness to give Corbyn a chance more than it has from the left refusing to engage with the centre. Regardless, both have their own demons to exorcise if we are to move forward from here.
