I don't even know why I bother responding to your post, but Britain's a very different country from the US.
First of all, most of England is liberal compared to the US. Why else would the elect the leaders they do?
Secondly, Thatcher's own party gave her the boot in 1990.
She wasn't that popular with the party Establishment from the beginning, but she didn't have much of a base left by the time she was done.
40% of the country hated her all along and by the time she left only 20% approved of her.
There is some respect for her abilities in Britain, but Thatcher was never as popular with the British people as she was with US conservatives.
Polls are for feeble minded dolts. Thanks for proving it.
