We've had two female Prime Ministers before her, one of whom was quite successful as a politician (bloody awful for the country though).
It wasn't sexism, she is genuinely completely useless. Fractally shitty, in that if you examine any part of her stint in politics it is every bit as shitty and inept as the whole.
It's been clear for a long time that she's totally incompetent, the part that mystifies me is why Tory MPs gave members the choice of her or Sunak. That outcome was also obvious, for obvious reasons. Some of the other candidates were at least unknown quantities and at least one even gave the impression of being not entirely mad.
Not just sexism. I mean, I'm sure it doesn't help but the UK has had many important female politicians, and will have more, it's just that XX doesn't magically make you competent.
Boris knew the facts and lied about them. He knew where he was last Wednesday (in your bed, fucking your wife) and he's got enough smarts to figure out that a confident lie about having to work late will help him. That's not a great feature in a leader, but hey, he's at least got some idea what's going on. A liar, a cheat, a real piece of shit, but not the least competent person ever to be elected.
Liz has no idea what the facts are, and seems oblivious. Where was she last Wednesday? She's hoping you will remember because she already forgot. Why did her own constituents elect her? What was she running against? Was it the lettuce?
Why can't the Tory party do better, that's the real question. How is it that Liz Truss was on offer to the party members as Prime Minister in the first place ? They only have to send two candidates. Send two serious options, if you can't do that, why are you pretending to be a party of government?
Also, if you look at Scotland, we've had Nicola Sturgeon as First Minister for six years or so now (in which time she's seen four Tory PMs come and go), and she is so popular in the last-but-one Scottish Parliament elections her party got an overall majority, in a voting system designed to prevent any one party getting an overall majority.
Edit: I'm sure objectively she was bad, but yeah.
