Her point is that, in his belief structure, Obama essentially is not an American. She believes he views himself instead as a globalist, an internationalist. She says:
He is hard put to sound convincingly like the leader of the nation, because he is, at heart and by instinct, the voice mainly of his ideological class.
How does that "ideological class" view the United States?
It is held as revealed truth that the United States is now, and has been throughout its history, the chief engine of injustice and oppression in the world.
That explains Obama's compulsion to go around the globe apologizing for our nation's behavior at home and abroad.
