Where's the vision?

The President has a duty to set the vision for our country. When John F. Kennedy set the vision to land on the moon he led America with a plan to greatness. As our country is on a course to defaulting for the first time in our history our President has not led or offered a specific plan of his own. I agree with Yale professor David Bromwich that Obama has always preferred the symbolic authority of the grand utterance to the actual authority of a directed policy...protracted moods of extreme abstraction seem to alternate with spasmodic engagement.
