Barack Hussein Obama was sworn into the office of the President of the United States on January 20th of this year.
The Nobel Committee ceased taking nominations on February 1st. Same year.
Now, check my math, but I believe that is about eleven (11) days -- more or less.
Prior to being President, Barack Obama had a fairly normal run as a Federal Senator -- some more lustrous, some less so -- and before that he was a State Senator and a "community organizor".
