Obama deserved the Nobel Prize?

I don’t want to start a blogo-war with a good friend, but I am less certain than Joel Rubin at Democracy Arsenal that President Obama earned the Nobel Prize.  According to Rubin,

Last November, Americans voted overwhelmingly for change. We elected a man who represented that change, both in his personal story and his political outlook. Less than one year since that historic election, the man that Americans sent to the White House has dramatically improved how our country is viewed overseas while setting in motion a significant number of events that are advancing both our national security and the cause of peace.

For these efforts, he deserved the Nobel Peace Prize.

In other words, President Obama won the Nobel Prize because he is not George W. Bush and because of what he plans to do. I am not convinced these are particularly good reasons.
