That may be true in fact, but it certainly isn't true in perception. Corbyn, fairly or unfairly, has been unable to escape the perception that he is an extreme socialist that's about to go all Venezula on the UK economy. Fact ought to triumph over perception, but it doesn't in this election of lies and counter lies.
It's odd really, as pretty much every election I remember the press say equivalent about Labour. I remember Tony Blair being compared to Stalin in the 90's!
Labour have batted off those questions pretty well. They've costed a manifesto and it holds together quite well, (there's enough academic rigour in it). The 1.2 trillion thing was dropped very early and they were unable to get it passed through the civil service, as they knew it was nonsense.
Labour struggle primarily on Brexit. It's the big weakness. Secondly on being indecisive in addressing some of the accusations (or slurs depending on perspective) sent their way.
It's funny really, I watched a Netflix show on the Cortez woman in America. In honesty, she's not particularly likeable, certainly nowhere near as genuine and likeable as Corbyn is, but there was a moment in the show where her opponent tried a slur on her, saying she'd visited a democrat who slashed a woman in the face. She was incandescent with rage and went on the counter attack, saying while she may have been there, how did she know who was there or what they had done, and it's disgraceful to use such language about her. Say what you want on her, but the anger was palpable and people react to that sort of stuff, they see it's probably not true.
To me Corbyn should have been equally angry very early on when the anti-Semitism and IRA accusations came out. If someone accused me of being a racist I'd respond very angrily and go on the counter offensive. He just kind of ignored things. It was a big mistake.
They are the big weaknesses for Labour.
