I dont see why not. Corbyn threatened to upset the apple cart and they reacted with fury.
I followed Corbyn's career for many years, long before he became leader. Someone who attended numerous meetings with him in London once told me there were two things to bear in mind about him:
1. He has a huge ego.
2. He hates to be outflanked on the left, by friend or foe.
Nothing unusual in the first one amongst politicians, at least most of the ones I've met, but add the two together and that's the prism though which I've always viewed Corbyn's various actions and prognostications, rightly or wrongly. I believe it was a tragedy that we were saddled with him as leader at the only time in my lifetime that there was a genuine chance of a left wing Labour government. I understand he's a very good constituency MP - in my view he should have stayed as one.
I know and wouldn't expect you or any of his many supporters to change your minds about him - I once held Tony Benn, a much greater politician/leader/campaigner/teacher/person, in similar esteem and would argue with the same passion that you show in defence of him.
Benn, though, had scant chance of becoming Prime Minister, even if he'd been Labour leader: peak period Thatcher stood in the way - almost unbeatable at the time. Corbyn in contrast had the wretched Mrs May and a Conservative Party that ran the worst campaign in political history to beat: have you ever known any party having to repudiate its own manifesto just two days after releasing it to great fanfare? And then he allowed himself to be suckered into agreeing to a 'Brexit' election, thus saddling us with this hapless and incompetent government for five years! A complete failure of leadership and judgement.
Incidentally, did you ever see the press/tv coverage Benn had to deal with? And he wasn't even party leader! Kinnock, too, had to put up with horrendous treatment by the media, so nothing unique in that to Corbyn.
