per our gal Peggy Noonan....
Mr. Obama is a writer, and he sees himself as a writer. It is an important part of his self-perception. He is the author of two books, the first of considerable literary merit. He loves words. It is in writing that he absorbs, organizes data, thinks his way through to views and decisions, all of which adds to the expectations for his speech.
Thanks Peggy. Just another way of saying that he is a good BS’er. The world's full of them.
