That was the thing with Corbyn though - the vast majority of the "criticisms" that the public came out with were things they'd read / heard rather than developed themselves. He (and Labour) did face huge problems in that respect, but anyone seeking to reverse the course that the country was on - which has led us to this dark place - would have faced that. Hell, even the diet / sugar free reform that Starmer represents is facing many of the same problems despite the fraud and ineptitude of this regime being even more obvious.
I'll be perfectly honest here, many of Corbyn's staunchest supporters that I personally know helped put me, and a great deal many others I know, right off him and labour. Really brought out the worst in some people becoming party members and aligning with momentum.
Literally calling people on Facebook, Twitter or even in the pub c you next tuesdays if they so much as debated or questioned a Corbyn performance or a policy etc. Out came the accusations of being swayed by the media or a 'tory' lol. Super defensive and paranoid stuff. Really cult like behaviour in some quarters.
I know several people swayed to vote 'not Corbyn' by them and their ilk. For the record I gritted my teeth and voted labour. So yeah, maybe not just a leader problem, but the folk associated with him being so obnoxious it doesn't win hearts and minds.
Momentum just came across as weapons by and large in my personal view. Who needs the media to do all the work when his support were so off putting as well?
Add it all together with media attacks he was never going to win an election. I've said before, there are some hideous folk on the left.
