David Axelrod's Theory Of Leadership
“If the president weren’t tough, if the president weren’t committed, if the president didn’t believe that this was an imperative for the future of American families, businesses and the sustainability of our budget, this thing would have been dead six months ago,” David Axelrod, Mr. Obama’s senior adviser, said in an interview. “I would love to live in a world where the president could snap his fingers or even twist arms and make change happen, but in this great democracy of ours, that’s not the way it is.”
So, Obama gets credit for the process remaining a process, even though he essentially handed the process off to Congress. But that change stuff? A president can't do that. A candidate can campaign on it, but an elected president can't actually do it. Or maybe it was something else.
