The author casts this as a diatribe against Obama for being a flip-flopper. I read the story and see a candidate who takes in new facts and is not afraid to modify his position to align with the best available information. Much of the US was mis-informed as to the overall effect of corn based ethanol, which helps energy independence, but damages the scene of carbon emissions for global climate change and endangers the supply of affordable food. I would praise him for changing his stance. The story is in support of Clinton, but does not say whether she has enhanced her position based upon the latest information. If they are not for conservation, solar, and limiting population growth, they have not arrived yet. If they are mutable, there is still a chance for bottom-up democracy to inform and perfect the choices.
