I am not sure that those who voted to leave would have been swung by economic arguments from Corbyn, which seems to be the complaint from the party - that he only campaigned about environment, equality, workers rights and peace.
The leave vote feels desperately like a huge 'F Off' to big business and bureaucrats, fed up with the bankers and the multinationals reaping huge profits while workers saw their pay, in real terms, diminished their communities dessimated and their services overstretched. Labours's problem was not talking about the economy, if anything it was missing the opportunity at the last election to really connect with the Old labour voters, who have had their worlds systematically destroyed by successive privatisations, closures and under investment and were looking for someone to blame - sadly it was UKIP who stepped in to tell them that immigration and the EU was the problem and exploited their need for hope, rather than Labour telling them that their welfare and community was worth investing in. The Tories were doing plenty of economy talking, they wheeled out experts left right and centre, but the people rather chose to protest with their vote. Talk of the economy means little to those who already have nothing, or feel they have nothing, but if they can give the establishment a kicking as they go down, they make that protest. Its just a terrible, terrible shame that they chose to protest over something that has such serious no way back consequences. Alot of those voters seem to come from traditional Labour heartlands, those voters SHOULD have been voting Labour, but somewhere along the way (probably when Blair got into bed with big business and seemed to morph the party into something more blue than red) they lost faith that Labour had their interests at heart. There are a hell of alot more poorly paid people in this country than those served by the Tories. And now that the veil has been lifted and they can see that they have been completely lied to I suspect that they could be swung back Labour's /way, given the right message. And actually allowed to HEAR the right message, because I fear the press has played a huge role in it all. I went to see Corbyn speak in Hastings. I also heard how his speech was reported on the local news. The 2 didnt correspond in any way that I recognised. And this has been pretty much constant since he was put onto the ballot paper last year (pretty similar goings on with Bernie Sanders in the US, who many people havent even heard of) At least if it were an election campaign they would not be able to ignore and sideline him, and he would have to be given equal airtime through the media.
The breakdown of votes suggest that Labour did about the same as the SNP in regards 'remain' votes, and yet they are being viewed as successful, whereas Labour a failure. At least Corbyn's campaign was honest, based on facts rather than scaremongering or false promise. He was realistic in that he admitted the EU wasnt perfect, but we were stronger within, and were in a far better position to negotiate. He warned of the risks of handing power to the more right wing faction of the Tory party.
On Radio 4 this morning I heard them discuss with George Osbourne that they needed a more 'low-key' Remain supporter as a potential MP, and yet this is the same accusation that is levied at Corbyn - that he wasnt all flags and klaxons, making huge claims about situations we can only speculate at.
Just my opinion though, I appreciate that others have been party members for much longer and probably come from a diferent perspective. Ive heard a rumour that Oct 13th has been pencilled in for a general election (whether tis true or not is yet to be seen) and it seems a huge shame to miss an opportunity to connect with those grass root ex Labour voters (Im pretty sure he has much of the young/new voter support) as they realise that UKIP/Boris wont deliver
