Considering how long ago, around February 2009, nomination(s) was/were made, you're left with the feeling that there's no area in which politics does not feature, be it in science, sports, arts or even in politics.
"for his extraordinary efforts to strengthen international diplomacy and cooperation between peoples"
I'm trying to recall what "extraordinary effort" towards world peace could have been made by the few-days-new US President by February 2009. He is, right now in a press interview, saying he is undeserved, and that challenges (for world peace) can't be met by any one leader, or any one nation. And, as if bombing Afghanistani and Pakistani women and children to oblivion is not enough, US/NASA bombs the moon in search of water on the same day Obama wins the Peace Nobel Prize!
Will UK Prime Minister, Gordon Brown receive the 2009 Nobel Prize for Economic Sciences? We'll know on Monday 12 October 2009.
