First, it is concerning to me that she would essentially use a sort of code language. Real Leftists would recognize the line, and realize she is simpatico -- but most Americans would never catch on ... until the blogosphere, that is.
Frankly, when I heard Michelle Obama utter those words (and I have read Alinski's primer) I was only reminded of of the line often quoted by RFK: "Some see the world as it is today and ask why. I see the world as it could be and ask, why not?" Even I would not have recognized the line.
It is important to state that Saul Alinski was not merely a liberal. Those who are unfamiliar with him or his work will likely miss the significance of this. He was, indeed a radical, who believed -- as Stalin did -- that "the ends justify the means." Rules for Radicals was essentially a Bible for the Clintons and the Obamas.
