I don't know why some get so upset about it. Even assuming one hates the guy, and he flops in the general, Obama has been a huge public relations 'coup' for the USA, the biggest I recall in my lifetime, and according to my parents - their's. He has brought more goodwill that money could possibly buy.
Even if he does not get in, they should slap him in some high profile diplomacy post, even if just a showpiece... and milk his worldwide popularity like crazy...
