In Andrew Sullivan's Daily Dish today there is commentary by Kleiman, who points out that Obama is adhering to the FDR style of experimentation: Try it, see if it works, if not, scrap it and move on. This is part and parcel of Obama's progressive pragmatism. Pragmatism is the way of America: William James had declared us a nation of pragmatists in the early 20th century.
Howe and Strauss, authors of The Fourth Turning : An American Prophesy (Broadway Books, 1997) had predicted that in the election of 2004 or 2008, a Generation Xer (Obama is between Boomer and X, a Jones, actually, but close enough) would take the helm with a Nike slogan attitude ("Just Do It"). Obama is fulfilling exactly that which he ought to be. He is right on time.
