Corbyn will rightly shoulder the blame for making Labour un-electable.
100% this.
I have to be honest and say that the Labour manifesto is impressive in its ambition, its detail and the amount of work put in. I fundamentally disagree with some of the assumptions, but it is certainly defensible as a document.
The stark and damning problem is that it espouses a set of doctrines and policies which very broadly, the UK public does not want. I've been banging on about this for ages, and I am 100% convinced I am correct. Why? Because the country has been progressively getting richer over the past 50 years, with fewer and fewer people (as a percentage) in low paid, unskilled manual labouring jobs. Jobs where working conditions were terrible, worker-management relations were terrible, exploitation was rife and the unions had a vital role to play. And that is not the UK of today.
The majority of the electorate now have skilled jobs and have upwardly mobile aspirations. They do not identify with donkey-jacket-wearing union leaders and everything that goes with it. That includes widespread nationalised industries. People are not stupid: They remember how shit things were when these organisations were under public ownership. They remember British Leyland. They remember miners's strikes and steelworkers strikes. Sure there may be outliers, and people may have rose-coloured glasses about trains (they'd be wrong to remember them as being anything other than terrible). But people do not see the sense or the value in spending tens of billions on nationalising businesses because of some ideologically-driven bollocks about the state running everything.
They want better public services of course, but they understand that with everything there is a cost. And they are not so stupid to imagine that Labour can splurge money on an unprecedented scale and yet no-one other than a tiny percentage would ever have to pay for it. It is not credible and people rightly do not believe it.
They see Corbyn as a shouty protester who has contributed fuck all over his 40 years in politics, memorable only for the bad things: Hhis association with Hamas and support for the IRA; his refusal to condemn Russian attacks in Salisbury; his very questionable (at best) record on fighting anti-semitism. Outside the bubble of the increasingly desperate hard left and Marxists, he is widely despised.
He is the wrong man, with the wrong policies and until Labour get their heads around BOTH of these facts, Labour will never win a majority in a general election. Labour MPs know this and voted by 80% to get rid of him. The penny still needs to drop with the hard left and the Marxists.
