I think for those of us who aren't insanely ambitious, it's really hard to get inside the mind of someone like this. Presumably you go into politics at least partly because you want to change things for the better - not just for self-advancement - and therefore you should, surely, put up a fight against a policy that makes things worse for people.
So it's hard for those of us with a functioning moral compass to conceive of someone who thinks, essentially, "This is a terrible policy that will have a massively damaging effect on women's lives, particularly if they're poor or vulnerable, but I'm going to promote it because it means people in my own party are more likely to elect me leader."
I have no idea if that is her thought process. Perhaps she genuinely does believe it's all terribly complicated. Perhaps she genuinely believes that it's fine for men to go into women's changing rooms. Perhaps she genuinely believes that the government has the right to overrule the Supreme Court.
If she is doing this out of a cynical desire to be leader, she's not fit to be in government.
If she genuinely believes that women's rights don't matter, and that politicians can ride roughshod over the highest court in the land, she's not fit to be in government.
