Mrs. Clinton gets by with saying nothing, and never having to answer anything. I saw her blissfully yammering with Tim Russert on Meet the Press. She never was challenged by Russert to explaino exactly what she means by "you know", because frankly, I don't think she knows either.
She's really a very average thinker. She's been getting by on the same old socialist, Marxist, Saul Alinsky crap since her commencement speech and "Thesis" at Wellesley.
