I don't for one second imagine that everything she did is defensible, and I'm still not sure if I actually like her, but I respect her as a politician. Andrew Marr makes an interesting point by stressing that she genuinely did seem to believe that increasing home ownership/share ownership/borrowing for everyone would improve their lives, she just rather naively thought they'd be sensible about it.
While I'm not quite of the "I'd take her over Blair" school of thought, but that is where Maggie can get respect from me. She actually believed in what she was doing, her ideology was her ideology, she didn't do it to win votes, she didn't do it to be liked or to get on the news, she did it because she believed it. You can't say that of too many politicians nowadays.
