Unquestionably. I have a habit of getting Labour leaders wrong; I voted for Blair in ‘97 (never again, obviously, nor Brown), I liked Ed Milliband (still do, he seems a decent bloke). More recently I got suckered by both Corbyn and Starmer, initially thinking each had way more backbone and integrity than turned out to be the case.
I’ve learned my lesson. Just not my party. I’ll stick to prodding it with a stick from a safe distance.
PS I do still like some individual MPs, mainly the ones who break their career programming and actually speak with some moral conviction (Rayner, Lammy etc).
