I have significantly reqorked and expanded the article. It is not yet FA worthy yet but I am trying to make sure that each of the sect5ions work with each other. Can you take a look and tell me if you think I've explained why the events for Obama is relevant. I have tried to highlite things that have made the individual buildings stand out as much as possible. Please don't take any sources out though until we discuss on talk page. I've spent 10-15 hours researching and rewriting so I don't want to have ot redo anything.
