Again this isn't about Brexit in general but about the Labour's stance on it.
Officially the were supposed to support remain, their members support remain, their MPs support remain, their voters support remain and all overwhelmingly.
Corbyn is a Eurosceptic and that's the problem the are supposed to oppose the Tories and Brexit but Corbyn does whatever he can other than gleefully dancing in the street in support of finally leaving.
He didn't support his party in opposition leading to the referendum, in fact he went MIA during the critical weeks and days leading to it, he turns down the option for a 2nd referendum which the majority of his party supports and turns down the option for a people's vote on the final deal.
He did absolutely nothing as the leader of the opposition to bring forth legislation that would support the retraction of Article 50, a soft-Brexit with the possibility of rejoining the EU or anything that actually opposes the shit show that has been going on for the past 2 years.
The only thing he did it marginalize his party in the eyes of many Labour voters.
>The other issue is that the majority of Labour votes come from leave areas. That's the other part of the 52% problem. We can placate the members at the potential loss of our core voters.
The majority of labour voters want to remain, this was always the case now it's even more as over 1.4M labour voters that voted leave in the election now want to remain.
The crazy socialists that want the UK to leave the EU in order to get rid of the EU competitive laws so they could nationalize everything and finally have their venezuela are not the core of the Labour party they never were and hopefully never will be because that would be a dark day for the UK.
In the Brexit referendum 65% of Labour voters voted remain, 68% of LDs vote to remain, LD wasn't any more pro-remain than the Labour, both of them are now at around 80% support for remain.
