As a lifelong Labour Party member who voted twice for JC to be leader - yes. A whole lot worse. The fundamental problem the party has, doesn't reveal itself in raw poll numbers, but it is revealed by a more sophisticated analysis of those numbers. It's a problem that cannot be resolved to everyone's satisfaction. Much like Brexit really, but it isn't Brexit itself. I've read excellent articles discussing the problem in The Guardian, The Independent, The Times, The Irish Times, Frankfurter Allgemeine Zeitung, and by numerous well informed bloggers from quite a few foreign countries, but it's clear that even some Labour MPs don't get it yet. You won't find it talked about in our gutter press, the Daily Mail, Express, Sun, Telegraph etc; real information, with real facts and careful judgments, lie elsewhere.
Unfortunately, and you have to blame the gutter press and the BBC (I don't say that second bit easily), the Labour Party cannot have the debate with the public that's so needed, because it will be blasted out of existence by the flamethrowers of the gutter press, owned by Tory-supporting oligarchs and those who support them, the Paxmans and Humphryses that have infested the BBC for so long and driven out good, independent commentators like, most recently, Evan Davis.
We'll have to wait and see what happens in the general election. At least we, the Labour Party, are the only party with a fully worked out and costed manifesto in place, describing policies that are taken for granted as mainstream in Europe, EU country or not. Don't believe the lie that the EU doesn't allow e.g. state owned railways and all that crap. EU social policy is much more enlightened than that. We should be so lucky.
Yes, the Labour Party has changed so much recently, but not completely. Fortunately the Tory-light of Tony Blair's Third Way bilge has largely been rejected but there's still work to do.
Have a nice day one and all; at least it's cooler out there, 72℉ in my back garden in the East Midlands right now.
