You Sullivan haters will probably be surprised by this since you've incorrectly labeled him a "liberal", but he LOVED her. Good read from him on Thatcher linked below.
I was a teenage Thatcherite, an uber-politics nerd who loved her for her utter lack of apology for who she was. I sensed in her, as others did, a final rebuke to the collectivist, egalitarian oppression of the individual produced by socialism and the stultifying privileges and caste identities of the class system. And part of that identity – the part no one ever truly gave her credit for – was her gender. She came from a small grocer’s shop in a northern town and went on to educate herself in chemistry at Oxford, and then law. To put it mildly, those were not traditional decisions for a young woman with few means in the 1950s. She married a smart businessman, reared two children and forged a political career from scratch in the most male-dominated institution imaginable: the Tory party.
