Maybe he was damned if he did and damned if he didn't, but he's now left the door open for Labour to be more criticised by the MSM
He was damned either way. Can't you see, Tories and Boris have control over communications and the narrative? It does not matter which way he jumped, Boris had him either way.
As for Labour's abandonment of the all they were supposed to represent, it happened under Blair. Whoever said a few pages ago that the rot goes back much further than the Tory government was right. Tory-light Blair did huge damage to people's conceptions of what the left could be, should be and was. Then we actually got Corbyn in charge, a real socialist providing real policies that did all the things we needed: and I knew working class older people, who had grown up in a far more socialist state years ago, dismiss him as a "communist".
Starmer is no more successful than Corbyn at changing that issue with media and communications. After the combined Brexit disaster and election defeat, sold with all that gubbins as the worst defeat ever, blah blah blah as if MP representation in the Commons ever really means anything about the state of minds in Britain, the entire Left is acting as if it has no future and nothing to offer any more.
At risk of sounding grandiose, Britain has never needed the left so much, not since WW1 (makes a change from all the 'since WW2' tropes coming out). I hope they pull themselves together, ditch the stupid ideologies and go back to basics - policies and practicals. But the first thing they need to learn about is communications, and to stop giving up so easily.
