Don't think Anna Turley, or Sangria, wrote the comments. But seriously, perception to it, isn't it? You hear Mattinson in that interview I posted making the same points (interview was late last year) where voters were telling her that it wasn't that they were against something, they just couldn't understand why it was all Labour seemed to be talking about. As Anna Turley points out, if the images coming from the party are everyone waving a Palestinian flag while cringeing every time the party leader is next to a union jack then perceptions of the party will be shaped by that. And not in ways which will be favorable to getting elected across a wide part of the country. Doesn't mean you have to ditch wanting Palestinians having their own state etc. Does mean considering that it might be a bit niche as an offer to the electorate.
Perception, as you say - but I don't remember seeing 'everyone waving a Palestinian flag'. Saying that, I do take the point you're making.
We can't fall into the trap of having too narrow a focus on the problems, though.
If we look back over the electoral history of Hartlepool since the late 90's, there is a pattern of increasing combined support for the Tories/UKIP* broadly from 2010.
In 97, Labour had 60.7% of the vote compared to 25.2% Tory/UKIP. Was similar in 2001.
By 2005, the Labour share had fallen to 51.5%, but it was the LD's benefitting - they'd been around the 14% mark since 1983, but leaped to 30.4%. The Tory/UKIP combined was just 15%
After that the trend was generally one-way.
2010 - Labour 42.5% / Tory/UKIP 35.2%
2015 - Labour 35.6% / Tory/UKIP 49.9%
None of those elections had Labour people waving Palestinian flags, and Corbyn was still just an obscure, natty backbencher from the hard-left.
In fact, in 2017, the trend was temporality reversed. Labour got 52.5% to the Tory/UKIP 45.7%
That's a fantastic swing in anyone's book.
Sadly, it was very temporary. By 2019, the Labour share had dropped to 37.7% to the combined Tory/UKIP 54.7%, and only got re-elected due to the split of the Tory/UKIP vote.
And, of course, the further Labour vote share slump this year to 28.7% (interestingly, the Tory/UKIP(ReformUK) share also fell slightly to 53.1%.
I'm not arguing that the Corbyn tenure didn't damage Labour to some people.
I'm arguing that the issues leading to the Labour Party's demise in a growing number of traditional heartlands began well before his time as leader, and are much wider than him and his time in charge.
If Labour fail to realise this, they will never learn the lessons that have to be learned.
