I think there are different parts to this.
One the media presentation. The all give women MPs a harder time. Constantly going after her about self id wasn't because the media cares about the issue, it was to set her up to look stupid. And I am sure some stylist somewhere thought up the way she should dress would somehow be middle england enough to reassure voters. (They all have their styles, look at Nicola Sturgeon and her little suits, and Angela Merkel with her one suit but in many colours.)
Also, I doubt there are many on here who not what she did or did not say in her own constituency, and as others have said up thread she was defeated by the SNP surge. As she had already lost her seat once and only got it back on a few hundred, it was probably a bit stupid of the Lib Dems to elect her as leader.
Her problem was that having taken on the role of leader she then had to sell it to the public, not just the self id, but the committment to revoke (which many say as undemocratic). This was also Corbyn's problem and why he came over as a bit vague. He is a committed exiter but was forced through the "democratic" process of party conference etc., to push an agenda that others had compiled.
I just think that she had faults, but so do they all. It is just the media endlessly parroting each other. ie the terrible election for the Lib Dems. The reality is they increased their vote, and under a more representative result reflecting what people actually want the Lib Dems should have had over 70 seats. They got 12. SNP got 48, but should only have had 25!
The problem is even when we are aware of media slanting and making it personality politics, it still seeps in. Look how many people are saying when electioneering people were talking about Corbyn as being a Communist. Many of his policies were those of the McMillan Tory Government "You've Never Had It So Good".
