Mike Elliott gets it:
Thatcher's true genius was her relentless focus on making policy in support of a remarkably prosaic goal: to let middle-class folk feel that hard work would be rewarded in a better future for their children.
Just as important:
Though she was revolutionary in her intent, she could be remarkably pragmatic in her execution.
Obama's arrival does remind me of Thatcher's and Reagan's. Different time; different challenges; different philosophy. But it feels as historic to me; and maybe one day, that judgment will be confirmed. Or not.
