Wallace wasn't wrong about everything. Do you object to anything about the quote itself? Because, if not, what's your point? You could find Hitler quotes that sound like things Obama's said.* Although that would show you something, namely that Obama's rhetoric is so vague and meaningless that even a Nazi could agree with it.

* For example:

With profound distress millions of the best German men and women from all walks of life have seen the unity of the nation vanishing away, dissolving in a confusion of political and personal opinions, economic interests, and ideological differences. [Take out the word German and this is basically the core theme of Obama's stump speech.]
