Last week, New York Times columnist Bob Herbert wrote: "Who is Barack Obama? Americans are still looking for the answer, and if they don't get it soon - or if they don't like the answer - the president's current political problems will look like a walk in the park. ... Mr. Obama is in danger of being perceived as someone whose rhetoric, however skillful, cannot always be trusted. He is creating a credibility gap for himself, and if it widens much more he won't be able to close it."
