I do think the '91 election was salvageable, mostly by it being a khaki election and with a sufficiently radical Cabinet shakeup like the last existential crisis in the summer of '81. BG and I posit this scenario in our TL. However the safest way is simply to avoid pledging the poll tax in '87: after all, she herself called it "the flagship of the Thatcher fleet." It was just as consequential as "Read my lips", because it was a central pledge. Alternatively she steps down in the summer of '89 without all the ugliness. But that's so out of character for her as to be highly implausible.
It really wasn't you know. She had gone mad by this stage, ignoring her own cabinet and believing herself to be infalible. She had lost the support of so much of her party that the infighting would have carried on into the next election, even more so if there was a radical cabinet shake-up. Getting rid of her was the Tories only chance.
In her memoirs she basically alternates between admitting that she was ideologically incompatible with Scots to saying "they don't know how good my economic policies made it for them with the new service sector." I don't think anyone disputes the ideological part. Then her biographers have all sorts of (IMO bigoted) psychobabble about a culture clash between a Middle Englander suburbanite and working-class Scots with a socialist dependency culture.

I'm paraphrasing John Campbell, before the Scots here go apeshit on me.
This is not to go apeshit at you, but that is so wrong it hurts. There was certainly an ideological difference, Scots tend to have more social consiense, even in the Tory party than Thatcher. As for the working-class, council house thing, well the Tories traditionally won the non, working-class seats in Scotland, in areas such as Ayr, Stirling, Perth, parts of Edinburgh and Aberdeen. What she did was to lose the Tory party its working class support in Scotland, either to Labour or the SNP, the middle class to the SNP and the Lib Dems. She was for the Tory Party north of the border a huge disaster.
Thacher because she was the only real PM since Eden.
She was real something, certainly.
