When Lincoln got to Washington after being elected President, the feeling in Washington that this guy has no idea what he is doing. Well it turned out that he was the only one in Washington who knew exactly what he was doing. For Obama it is the exact opposite.
Obama has not yet taken office, so how can anyone say he doesn't know what is going on?
In the early to mid-stages of the Civil War, when the Union was getting its butt kicked in many battles, most people thought Lincoln was incompetent. But, putting that aside, opinion change with circumstances. Obama needs to change the circumstances.
